Need help to configure shardsWhitelist in Solr 6.6. I have the below line in Solr.xml
<str name="shardsWhitelist">${solr.shardsWhitelist:}</str>
And I added the following in solrconfig.xml
<requestHandler name="/select" class="solr.SearchHandler">
<shardHandler class="HttpShardHandlerFactory">
<int name="socketTimeOut">1000</int>
<int name="connTimeOut">5000</int>
<str name="shardsWhitelist">https://<URL1>/solr/core0,<URL2>/solr/core0,<URL3>/solr/core0</str>
</shardHandler>
But, I can’t get the solr to acknowledge the configuration:
HttpShardHandlerFactory shardsWhitelist not configured but required (in lieu of ZkController and ClusterState) when using the 'shards' parameter. set -Dsolr.disable.shardsWhitelist=true to disable shards whitelist checks
Make sure to NOT use https/http.
${solr.shardsWhitelist::PORT/solr/CORENAME,:PORT/solr/CORENAME}
Example: ${solr.shardsWhitelist:something.com:8985/solr/core_0,something.com:8985/solr/core2}
You must specify the shardHandlerFactory element.
The shardHandler element is incorrect.
<requestHandler name="/select" class="solr.SearchHandler">
<shardHandlerFactory class="HttpShardHandlerFactory">
<int name="socketTimeOut">1000</int>
<int name="connTimeOut">5000</int>
<str name="shardsWhitelist"><URL1>/solr/core0,<URL2>/solr/core0,<URL3>/solr/core0</str>
</shardHandlerFactory>

I have defined my CustomQueryParser in my RequestHandler.
Below is the RequestHandler part of the code in solrconfig.xml
<requestHandler name="/browse" class="solr.SearchHandler">
<lst name="defaults">
<str name="defType">customparser</str>
<str name="echoParams">explicit</str>
<str name="qf">body_txt manu2</str>
<str name="q.op">AND</str>
<!-- <str name="mm">100%</str> -->
</lst>
</requestHandler>
And below is the queryParser part of the code in solrconfig.xml
<queryParser name="customparser" class="com.mycompany.lucene.search.QueryParserPlugin"/>
I have ensured that the jar file associated to the QueryParserPlugin is loading.
But when I make a query the correct documents are not reflecting.
Is there a way I can print from within my CustomQueryParser jar to the solr.log to know if it is being invoked?
Also how do i get this to work?
Have been struggling with this since quite a few days. Please Help !
Thanks
I've followed this to set up shard in Solr. As per this topic "Testing Index Sharding on Two Local Servers", I was able to query into shard and get the result (somehose:port1/solr/select?shards=somehost:port1/solr,somehost:port2/solr&indent=true&q=helloworld
).
In that page it is also mentioned that "Rather than require users to include the shards parameter explicitly, it is usually preferred to configure this parameter as a default in the RequestHandler section of solrconfig.xml."
So, I made the changes in solrconfig.xml of the solr instance which is running on port1
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">text</str>
</lst>
<lst name="shards.info">
<lst name="localhost:port2/solr">
<long name="numFound">1333</long>
<float name="maxScore">1.0</float>
<str name="shardAddress">http://localhost:port2/solr</str>
<long name="time">686</long>
</lst>
<lst name="localhost:port1/solr">
<long name="numFound">342</long>
<float name="maxScore">1.0</float>
<str name="shardAddress">http://localhost:port1/solr</str>
<long name="time">602</long>
</lst>
</lst>
Now, I'm trying to hit somehost:port1/solr/collection1/select?q=helloworld&wt=json&indent=true
but I'm not getting the desired responce. Please let me know what I'm missing here?
You can't just copy the content from the response into your configuration file - those two formats are completely different. The reference is to the fact that each entry in the defaults section is added to the query string (unless they're provided there already - there are also options if you want to force a certain value that can't be overridden).
<requestHandler name="/selectdistributed" class="solr.SearchHandler">
<lst name="defaults">
[...]
<str name="shards">somehost:port1/solr,somehost:port2/solr</str>
</lst>
</requestHandler>
.. should do what you want. This will add shards=somehost:port1/solr,somehost:port2/solr to the query string of all the requsts that go through that handler.
The following query works well for me
http://[]:8983/solr/vault/select?q=VersionComments%3AWhite
returns all the documents where version comments includes White
I try to omit the field name and put it as a default value as follows :
In solr config I write
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">PackageName</str>
<str name="df">Tag</str>
<str name="df">VersionComments</str>
<str name="df">VersionTag</str>
<str name="df">Description</str>
<str name="df">SKU</str>
<str name="df">SKUDesc</str>
</lst>
I restart the solr and create a full import.
Then I try using
http://[]:8983/solr/vault/select?q=White
(Where
http://[]:8983/solr/vault/select?q=VersionComments%3AWhite
still works)
But I dont get the document any as answer.
What am I doing wrong?
As far as I know you should only have the <str name="df"></str> declared once in your requestHandler
Typically what I do is copy all the fields that i want to search into a default search field called text.
schema.xml:
<copyField source="name_t" dest="text"/>
solrconfig.xml
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="q">*:*</str>
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">text</str>
</lst>
</requestHandler>
If this is not good enough, you can always search other fields using a dismax search with the qf declaration like so:
http://localhost:8983/solr/vault/select/?q= White&defType=dismax&qf=PackageName+Tag+VersionComments+VersionTag+Description+SKU+SKUDesc
I use spellcheck component and when I request solr I have results. But if I use spellcheck.q, i haven't result.
Someone has an idea ?
Thanks
<!-- The spell check component can return a list of alternative spelling
suggestions. -->
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">textSpell</str>
<lst name="spellchecker">

<str name="field">spellCheck</str>
<str name="spellcheckIndexDir">./spellchecker</str>
<str name="buildOnCommit">true</str>
<str name="accuracy">0.4</str>
<float name="thresholdTokenFrequency">.0004</float>
</lst>
</searchComponent>
<!--<queryConverter name="queryConverter" class="solr.SpellingQueryConverter"/>-->
<!-- Handler par défaut -->

</lst>
<arr name="last-components">

<str>spellcheck</str>
</arr>
</requestHandler>
Have you added your spellcheck component to the corresponding request handler (in solr config), set spellcheck parameter to true (or on) and configured the correct dictionary to use (if its name different than "default")?
If you don't use the spellcheck.q parameter, then the default is to use the q parameter (from http://wiki.apache.org/solr/SpellCheckComponent#q_OR_spellcheck.q). From that wiki:
Essentially, if you have a spelling "ready" version in your application, then it is probably better to send spellcheck.q, otherwise, if you just want Solr to do the job, use the q parameter
The reason that it works if you change the definition of the field type is probably due to the new field type being "spelling ready". It would help if you posted the query you are using and the relevant lines in the schema.xml.
I have indexed my database tables into solr using DataImportHandler. Now when I query the server it shows me that the number of results found 665. But when i try to assign it to beans like List itemList = rsp.getBeans(Item.class), it is giving me only 10 results.
Can some one help me out on this.
Thanks in Advance.
When you don't define the amount of rows (documents) to fetch, Solr defaults to fetching 10 documents, as explained in the docs.
By default Solr returns only 10 Documents. If you want to fetch all documents, you will need to update solrConfig.xml file of Core (path : /solr/server/solr/core_name/conf/solrConfig.xml) :
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10000000</int> <!--you can update it to some large value that is higher than the possible number of rows that are expected.-->
</lst>
</requestHandler>
You might have to edit your solrconfig.xml.
There change the "/select" Request Handler like this.
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">1000</int> <!-- Change this as you want -->
<str name="df">text</str>
</lst>
</requestHandler>
