When I try to do import of schooLocationDetails solr core, I get below error . Using Solr 5.3.1
Exception while processing: opportunityDetails document : SolrInputDocument(fields: []):org.apache.solr.handler.dataimport.DataImportHandlerException: org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://:<solr_pwd>#<solr_server>:<solr_port>/solr/locationCore: org.apache.solr.search.SyntaxError: Cannot parse 'locationId:': Encountered "" at line 1, column 22.
Below is my data-config.xml for the solr core schooLocationDetails.

You have to add the entity referencing the value inside the other entity. When they're two separate entities, they can't reference each other values (and they'll be imported after each other instead).

<doc child_1/>
<doc parent_1/>
<doc child_2/>
<doc parent_2/>
and i see aheryan's anwers , it should be right , i can use child=true
am i miss something ?
thanks
The child docs are returned together with parent docs if you just do a general query. As a flat list. So, that's probably what you are seeing.
The easiest way to check whether you got nested documents is to look at the value of the _root_ field, as the value will be the same for all documents in the parent/child hierarchy block.
You could also search for parent documents only and use Child Document Transformer to list its children.
I have a very strange problem with Solr 4.6.0.
The uniqueKey field "id" contains a hash for every document instead of my string value. If add just one custom document with the update request handler in the Solr admin I get for example the ID value "book_45" that I specified, so that is correct.
But when I do a full import with the DIH (data import handler) then the id field contains a hash for every document like "[B#53bd370f" instead of my custom value. So the problem must be in the DIH.
My import script:

The id field in my schema.xml (which is the same as in the default shipped core collection1):
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<uniqueKey>id</uniqueKey>
Does anyone know what I am missing?
the [B#53bd370f is not a hash, but the result of a byte[].toString(). Whatever Mysql is returning is being treated as a byte[] instead of a String.
Try casting the id to varchar or char like this:
SELECT cast(CONCAT('book_', b.id) as CHAR) AS book_id...
I'm trying to import the allemanic wikipedia xml-dump. I specified some regex rules to ignore wikipedia pages like categories, files, templates, ... This configuration does work without any problems.
But then I wanted to restrict the indexing to documents that have a contents field with a length of at least 200 characters. But I cannot think of any way to do it. I tried some regex but then the indexing would always instantly fail (something like (.*){5} doesn't seem to be supported?).
Does anyone know a regex that is supported by solr to skip documents with only 200 or less characters? Or is there any other way to achive this behaviour?

Firstly, (.*){5} will match exactly 5 characters. (.*){5,} will match five or more. So for 200, it would be (.*){200,}.
If this doesn't work, it is reasonably easy to write a custom transformer:

You can try different things:
Try setting the batchSize property. If you tune it correctly, you can increase the performance of your datasource.
SELECT * is ALWAYS slower than providing the columns you need (even if you need all columns). I would suggest using SELECT PRODUCT_ID, NAME, ... in stead of using *
Why do you have the entities b, i and s? You don't use the fields from it, so I don't think they're very useful
Try using the CachedSqlEntityProcessor for your sub-entities. It will only retrieve the data once and re-use it for each subenttiy.
Can your product belong to more than 1 category (is it a multivalued field?), if not, then writing one query using JOINS is faster than writing multiple entities.
EDIT: I suggest seperating this thing into 2 questions because now it's really weird for other people to read your new question with my old answer.
I don't think you can choose where the CachedSqlEntityProcessor will put his cache (it's always in memory I think). The problem with your 8 hours of data import is that, because we're talking about a lot of records, a lot of queries will be used (every subentity uses its own query).
The solution to your problem is to remove the subentity and in your parent entity add the query of your subentity as a comma seperated list. I suggest looking at this answer.
If you do this, all your specifications (for examples) will be stored inside one column as a comma speerated list. You can then use a Solr ScriptTransformer to split the values and create multiple values.
This limits the number of queries to 1 big query and will also limit the use of RAM since it will parse each query individually. I have no clue what the performance will be, because you will have to parse each entity individually.
If this doesn't work I don't think there is a better solution than to wait 8 hours for the data import to complete. You can't expect that Solr will index it all in 1 2 3. You can try using a cronjob to run this task over night.
