solr dataimport not working for URLdatasource - solr

This is my data-config.xml
<dataConfig>
<dataSource name="a" type="URLDataSource" encoding="UTF-8" connectionTimeout="5000" readTimeout="10000"/>
<document name="products">
<entity name="images" dataSource="a"
url="file:///abc/1299.xml"
processor="XPathEntityProcessor"
forEach="/imagesList/image"
>
<field column="id" xpath="/imageList/image/productId" />
<field column="image_array" xpath="/imageList/image/imageUrlString" />
</entity>
</document>
</dataConfig>
This is the schema.xml
<field name="id" type="string" indexed="true" stored="true" required="true" />
<field name="image_array" type="text" indexed="true" stored="true" multivalued="true"/>
But when I try to deltaimport, none of the documents get added.
Any help will be highly appreciated.

Well first off, your XPath says imageList and your XML says imagesList ...

How to index related tables in solr

I am trying to index my database for a question answer website. To start off, I want to index the questions and answers table which has a one to many relationship. I would expect solr to return documents like:
{
'question_id': 1,
'question': 'Is this a question?',
'answers' : [
{
'answer_id': 1,
'answer': 'Maybe'
},
{
'answer_id': 2,
'answer': 'yes it is'
}
]
}
What configuration do I need to achieve this?
I've gone through Configuring the DIH Configuration File tutorial.
Below are the configurations I've tried:
CONFIG 1
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/questionsdb" user="root" password=""/>
<document>
<entity name="questions"
pk="id"
query="SELECT id, title FROM questions">
<field column="id" name="question_id"/>
<field column="title" name="title"/>
<entity name="answers"
pk="id"
query="select id, answer from answers where qid='${questions.id}'">
<field name="answer_id" column="id" />
<field name="answer" column="answer" />
</entity>
</entity>
</document>
</dataConfig>
QUERY OUTPUT:
CONFIG 2
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/questionsdb" user="root" password=""/>
<document>
<entity name="questions"
query="SELECT questions.id as question_id, questions.title as question, answers.id as answer_id, answers.answer as answer FROM questions JOIN answers ON questions.id = answers.qid">
<field column="id" name="question_id"/>
<field column="title" name="title"/>
<field name="answer" column="answer" />
<field name="answer_id" column="answer_id" />
</entity>
</document>
</dataConfig>
QUERY OUTPUT:
I'm using solr 8.6.
EDIT 1:
Updated my managed-schema file to use multiValued="true":
<field name="question" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="question_id" type="pint" indexed="false" stored="true" multiValued="false"/>
<field name="answer" type="string" indexed="true" stored="true" multiValued="true"/>
<field name="answer_id" type="pint" indexed="false" stored="true" multiValued="true"/>
The output indexes the answers now but the answer and answer_id come up as a list.
Is it possible to restructure them to be returned as a list of dictionaries as given in the example structure above?

solr does not import fields other than id

I am using Solr DataImportHandler module. Here is my config;
<dataConfig>
<dataSource type="JdbcDataSource"
name="sql"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost;databaseName=AdventureWorks2008;integratedSecurity=true;"/>
<document>
<entity name="Person" dataSource="sql"
pk="BusinessEntityID"
query="select BusinessEntityID,FirstName,LastName FROM [Person].[Person]"
deltaImportQuery="select BusinessEntityID,FirstName,LastName FROM [Person].[Person] WHERE id='${dih.delta.id}'"
deltaQuery="SELECT BusinessEntityID FROM [Person].[Person] WHERE ModifiedDate > '${dih.last_index_time}'">
<field column="BusinessEntityID" name="id"/>
<field column="FirstName" name="firstname"/>
<field column="LastName" name="lastname"/>
</entity>
</document>
</dataConfig>
for some reason, only id field is importing but not the rest.
What would be the reason? Am I missing something?
You might have missed the below entries in the schema.xml file
<field name="id" type="string" indexed="true" stored="true" required="true"/>
<field name="firstname" type="string" indexed="true" stored="true"/>
<field name="lastname" type="string" indexed="true" stored="true"/>
Here type for id can be int. Just check what you want.
<field name="id" type="int" indexed="true" stored="true" required="true"/>
Make sure your Id and unique field is Proper.
I was facing same issue, change Pk and unique field name and it's working fine.

Indexing wikipedia with solr

I've installed solr 4.6.0 and follow the tutorial available at Solr's home page. Everything was fine, untill I need to do a real job that I'm about to do. I have to get a fast access to wikipedia content and I was advised to use Solr. Well, I was trying to follow the example in the link http://wiki.apache.org/solr/DataImportHandler#Example:_Indexing_wikipedia, but I couldn't get the example. I am newbie, and I don't know what means data_config.xml!
<dataConfig>
<dataSource type="FileDataSource" encoding="UTF-8" />
<document>
<entity name="page"
processor="XPathEntityProcessor"
stream="true"
forEach="/mediawiki/page/"
url="/data/enwiki-20130102-pages-articles.xml"
transformer="RegexTransformer,DateFormatTransformer"
>
<field column="id" xpath="/mediawiki/page/id" />
<field column="title" xpath="/mediawiki/page/title" />
<field column="revision" xpath="/mediawiki/page/revision/id" />
<field column="user" xpath="/mediawiki/page/revision/contributor/username" />
<field column="userId" xpath="/mediawiki/page/revision/contributor/id" />
<field column="text" xpath="/mediawiki/page/revision/text" />
<field column="timestamp" xpath="/mediawiki/page/revision/timestamp" dateTimeFormat="yyyy-MM-dd'T'hh:mm:ss'Z'" />
<field column="$skipDoc" regex="^#REDIRECT .*" replaceWith="true" sourceColName="text"/>
</entity>
</document>
</dataConfig>
I couldn't find in the Solr home directory. Also, I tried to find some questions related to mine, How to index wikipedia files in .xml format into solr and Indexing wikipedia dump with solr, but they didn't solve my doubt.
I think I need something more basic, guiding me step by step, because the tutorial is confusing when deals with indexing wikipedia.
Any advice to give some directions to folow would be nice.
For the data_config.xml
Each Solr instance is configured using three main files:solr.xml,solrconfig.xml,schema.xml,and the data_config.xml file define the data source when you use DIH component,this URL would be usefull for you :DIH.
About Solr home directory
You should start from here:https://cwiki.apache.org/confluence/display/solr/Running+Solr
Well, I've read many things on the Web and tried to collected as many information as possible. This is how I could find the solution:
here is my solrconfig.xml:
...
<!-- ****** Data import handler -->
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
...
<lib dir="../../../dist/" regex="solr-dataimporthandler-.*\.jar" />
Here is my data-config.xml: (important: it must be in the same folder of solrconfig.xml)
<dataConfig>
<dataSource type="FileDataSource" encoding="UTF-8" />
<document>
<entity name="page"
processor="XPathEntityProcessor"
stream="true"
forEach="/mediawiki/page/"
url="/Applications/solr-4.6.0/example/exampledocs/simplewikiSubSet.xml"
transformer="RegexTransformer,DateFormatTransformer"
>
<field column="id" xpath="/mediawiki/page/id" />
<field column="title" xpath="/mediawiki/page/title" />
<field column="revision" xpath="/mediawiki/page/revision/id" />
<field column="user" xpath="/mediawiki/page/revision/contributor/username" />
<field column="userId" xpath="/mediawiki/page/revision/contributor/id" />
<field column="text" xpath="/mediawiki/page/revision/text" />
<field column="timestamp" xpath="/mediawiki/page/revision/timestamp" dateTimeFormat="yyyy-MM-dd'T'hh:mm:ss'Z'" />
<field column="$skipDoc" regex="^#REDIRECT .*" replaceWith="true" sourceColName="text"/>
</entity>
</document>
</dataConfig>
Attention: The last line is very important!
My schema.xml:
...
<field name="id" type="string" indexed="true" stored="true" required="true"/>
<field name="title" type="string" indexed="true" stored="false"/>
<field name="revision" type="int" indexed="true" stored="true"/>
<field name="user" type="string" indexed="true" stored="true"/>
<field name="userId" type="int" indexed="true" stored="true"/>
<field name="text" type="text_en" indexed="true" stored="false"/>
<field name="timestamp" type="date" indexed="true" stored="true"/>
<field name="titleText" type="text_en" indexed="true" stored="true"/>
...
<uniqueKey>id</uniqueKey>
...
<copyField source="title" dest="titleText"/>
...
And it's done. That's all folks!

The simplest Solr DIH indexing

I'm trying to index data from a database in Solr using the DIH.
So I have modified the two config files as follows:
solrconfig.xml :
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
data-config.xml :
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/test" user="root" password="****"/>
<document>
<entity name="source_scellee" query="select * from source_scellee">
</entity>
</document>
</dataConfig>
source_scellee being the name of my table on my test database. It contains many fields.
Obviously, I'm trying to run nothing else than a simple test. When running http://localhost:8983/solr/dataimport?command=full-import&clean=false&commit=true I get the following result :
<str name="Full Dump Started">2012-01-27 12:27:01</str><str name="">Indexing completed. Added/Updated: 4 documents. Deleted 0 documents.</str><str name="Committed">2012-01-27 12:27:02</str>
<str name="**Total Documents Failed**">4</str>
Besides no warning nor error on the server logs. 4 is my number of records inside table "source_scellee". But it says all documents fail.
If I run a query from http://localhost:8983/solr/admin/
no results appear, at all !! How can I solve it ?
(":" shows no results)
Thank you for your help!!!
----edit---
I have added these lines to my schema.xml :
<field name="ID" type="int" indexed="true" stored="true" />
<field name="reference_catalogue" type="string" indexed="true" stored="true"/>
<field name="reference_capsule" type="string" indexed="true" stored="true"/>
<field name="organisme_certificateur" type="string" indexed="true" stored="true" />
<field name="reference_certificat" type="string" indexed="true" stored="true" />
<field name="duree_d_utilisation" type="string" indexed="true" stored="true" />
<field name="activite_nominale" type="string" indexed="true" stored="true"/>
<field name="activite_minimale" type="string" indexed="true" stored="true"/>
<field name="activite_maximale" type="string" indexed="true" stored="true"/>
<field name="coffret" type="boolean" indexed="true" stored="true"/>
<field name="dispositif_medical" type="boolean" indexed="true" stored="true"/>
<field name="forme_speciale" type="boolean" indexed="true" stored="true" />
<field name="exemption_cpa" type="boolean" indexed="true" stored="true"/>
<field name="marquage_ce" type="boolean" indexed="true" stored="true"/>
<field name="element_cible" type="boolean" indexed="true" stored="true"/>
However the result is still the same: no results when querying (I tried to restart solr, and to re-index all also)
------second edit---
I have tried the dynamic import
Now my data-config.xml looks like this :
<document>
<entity name="source_scellee" query="select * from source_scellee">
<field column="ID" name="ID_i" />
<field column="reference_catalogue" name="reference_catalogue_s" />
<field column="reference_capsule" name="reference_capsule_s" />
<field column="organisme_certificateur" name="organisme_certificateur_s" />
<field column="reference_certificat" name="reference_certificat_s" />
<field column="duree_d_utilisation" name="duree_d_utilisation_s" />
<field column="activite_nominale" name="activite_nominale_s" />
<field column="activite_minimale" name="activite_minimale_s" />
<field column="activite_maximale" name="activite_maximale_s" />
<field column="coffret" name="coffret_b" />
<field column="dispositif_medical" name="dispositif_medical_b" />
<field column="forme_speciale" name="forme_speciale_b" />
<field column="exemption_cpa" name="exemption_cpa_b" />
<field column="marquage_ce" name="marquage_ce_b" />
<field column="element_cible" name="element_cible_b" />
</entity>
</document>
1.) You can take a look to the statistics page to see, how much docs are indexed right now:
http://localhost:8983/solr/admin/stats.jsp
2.) The result of your search depends on your schema.xml, because there it's defined how docs are indexed/stored, which fields are processed and how searchs are handled on query time.
Please take a look at this file or post the field definition from the schema.xml and also the schema/design from your table source_scellee.
Does the columns and the fields have the same name?
//Edit: This should work, if coulmname and filedname are the same:
<document>
<entity name="source_scellee"
pk="ID"
query="select * from source_scellee">
</entity>
</document>
is having NULL values in data an issue ?
that depends on the destination field.
Are your running solr in an tomcat or someting like that?
Take a look in the Java EE Container output, like catalina.out or so.
I am pretty sure the issue lies in how the DIH is trying to map fields. Thanks for adding the information from your schema file... However, I believe that what you have done is added configuration that needs to be added separately to both the schema.xml and the data-config.xml for the DIH.
Based on the Full Import Example from the Solr Wiki, I would try the following.
schema.xml
<field name="ID" type="int" indexed="true" stored="true" />
<field name="reference_catalogue" type="string" indexed="true" stored="true"/>
<field name="reference_capsule" type="string" indexed="true" stored="true"/>
<field name="date_de_creation" type="date" indexed="true" stored="true"/>
<field name="organisme_certificateur" type="string" indexed="true" stored="true" />
<field name="reference_certificat" type="string" indexed="true" stored="true" />
<field name="duree_d_utilisation" type="string" indexed="true" stored="true" />
<field name="activite_nominale" type="string" indexed="true" stored="true"/>
<field name="activite_minimale" type="string" indexed="true" stored="true"/>
<field name="activite_maximale" type="string" indexed="true" stored="true"/>
<field name="coffret" type="int" indexed="true" stored="true"/>
<field name="dispositif_medical" type="int" indexed="true" stored="true"/>
<field name="forme_speciale" type="int" indexed="true" stored="true" />
<field name="exemption_cpa" type="int" indexed="true" stored="true"/>
<field name="marquage_ce" type="int" indexed="true" stored="true"/>
<field name="element_cible" type="int" indexed="true" stored="true"/>
data-config.xml
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/test" user="root" password="****"/>
<document>
<entity name="source_scellee" query="select * from source_scellee">
<field column="ID" name="ID"/>
<field column="reference_catalogue" name="reference_catalogue"/>
<field column="reference_capsule" name="reference_capsule"/>
<field column="date_de_creation" name="date_de_creation"/>
<field column="organisme_certificateur" name="organisme_certificateur"/>
<field column="reference_certificat" name="reference_certificat"/>
<field column="duree_d_utilisation" name="duree_d_utilisation"/>
<field column="activite_nominale" name="activite_nominale"/>
<field column="activite_minimale" name="activite_minimale"/>
<field column="activite_maximale" name="activite_maximale"/>
<field column="coffret" name="coffret"/>
<field column="dispositif_medical" name="dispositif_medical"/>
<field column="forme_speciale" name="forme_speciale"/>
<field column="exemption_cpa" name="exemption_cpa"/>
<field column="marquage_ce" name="marquage_ce"/>
<field column="element_cible" name="element_cible"/>
</entity>
</document>
</dataConfig>
There is a way to setup the schema.xml to dynamically add fields that it encounters by using some naming conventions. Please see the Dynamic Fields details in the Solr Wiki for more details and some examples of how this can be done.

Create index on two unrelated table in Solr

I want to create index between two tables, stock and auction. Basically I am working on a product site. So I have to create index on both tables. and they are not related at all.
In data-config.xml, that I created to create index, I wrote the following code
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/database" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</entity>
</document>
</dataConfig>
and the schema.xml contains the fields are given below.
<field name="stock_ST_StockID" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_StockCode" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_Name" type="string" indexed="true" stored="true" required="true"/>
<field name="stock_ST_ItemDetail" type="text" indexed="true" stored="true" required="true"/>
<field name="auction_iauctionid" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_rad_number" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_vsku" type="string" indexed="true" stored="true" required="true"/>
<field name="auction_auction_code" type="text" indexed="true" stored="true" required="true"/>
But this way the indexes are being created in wrong way as I put the other table data into the first table in data-config.xml. If I create two entity element like given below then the indexes are not being created.
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/lc" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
</entity>
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</document>
</dataConfig>
I did not get your answer, can you pls elaborate a little more. I also have the same requirement. I have two tables stock and auction. Basically I am working on a product site. So I have to create index on both tables. and they are not related at all.
Please help
Do you get any errors when indexing the data ??
The following data config is fine as you have two unrelated items.
<dataConfig>
<dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/lc" user="root" password=""/>
<document name="content">
<entity name="stock" query="select ST_StockID,ST_StockCode,ST_Name,ST_ItemDetail from stock where estatus = 'Active' limit 100">
<field column="ST_StockID" name="stock_ST_StockID" />
<field column="ST_StockCode" name="stock_ST_StockCode" />
<field column="ST_Name" name="stock_ST_Name" />
<field column="ST_ItemDetail" name="stock_ST_ItemDetail" />
</entity>
<entity name="auction" query="select iauctionid,rad_number,vsku,auction_code from auction limit 100">
<field column="iauctionid" name="auction_iauctionid" />
<field column="rad_number" name="auction_rad_number" />
<field column="vsku" name="auction_vsku" />
<field column="auction_code" name="auction_auction_code" />
</entity>
</document>
</dataConfig>
However, there are few things missing ?
Whats the id field for the entity ? As each document should have a unique id, the configuration seems missing above.
Also the id should be unqiue for the entites, else the stock and auction should overwrite each other.
So you may want the id append as stock_ & auction_
You can also add a static field as Stock and auction to your schema and populate them, which would help you the filter out the results when searching and hence improve the performance.
For Assigning the Ids -
You can use the following to create the id value - This should append the Stock_ with the ST_StockID field value.
<field column="id" template="Stock_#${stock.ST_StockID}" />
OR
Use alias in sql e.g. SELECT 'Stock_' || ST_StockID AS ID ..... as use -
<field column="id" name="id" />
