Hello, currently I am evaluating the block join children query parser. But it always returns "Parent query yields document which is not matched by parents filter".
What I have done so far: I have added the _root_ field to the schema: <field name="_root_" type="string" indexed="true" stored="false"/>. I have created a collection: curl http://localhost:8983/solr/admin/collections?action=CREATE&name=nestedPerson&numShards=6&collection.configName=mim I have enrolled this documents to the collection: curl http://localhost:8983/solr/nestedPerson/update?commitWithin=3000 -d ' <add> <doc> <field name="id">1</field> <field name="ps">PS1</field> <field name="deceased">false</field> <doc> <field name="id">2</field> <field name="cs">CS1</field> <field name="firstName">Martin</field> </doc> </doc> <doc> <field name="id">3</field> <field name="ps">PS2</field> <field name="deceased">true</field> <doc> <field name="id">4</field> <field name="cs">CS2</field> <field name="firstName">Stefan</field> </doc> </doc> </add>' Now I issue the following query: {!child of=ps:PS1}firstName:Martin. This returns an error message: "error": { "msg": "Error from server at http://bigdata2:8983/solr/nestedPerson_shard1_replica1: Parent query yields document which is not matched by parents filter, docID=0", "trace": "org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://bigdata2:8983/solr/nestedPerson_shard1_replica1: Parent query yields document which is not matched by parents filter, docID=0\n\tat org.apache.solr.client.solrj.impl.HttpSolrClient.executeMethod(HttpSolrClient.java:560)\n\tat org.apache.solr.client.solrj.impl.HttpSolrClient.request(HttpSolrClient.java:235)\n\tat org.apache.solr.client.solrj.impl.HttpSolrClient.request(HttpSolrClient.java:227)\n\tat org.apache.solr.client.solrj.SolrClient.request(SolrClient.java:1220)\n\tat org.apache.solr.handler.component.HttpShardHandler$1.call(HttpShardHandler.java:218)\n\tat org.apache.solr.handler.component.HttpShardHandler$1.call(HttpShardHandler.java:183)\n\tat java.util.concurrent.FutureTask.run(FutureTask.java:262)\n\tat java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471)\n\tat java.util.concurrent.FutureTask.run(FutureTask.java:262)\n\tat org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor$1.run(ExecutorUtil.java:148)\n\tat java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)\n\tat java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)\n\tat java.lang.Thread.run(Thread.java:745)\n", "code": 500 } Interestingly the block join parent query parser returns a valid result set for this query: {!parent which=ps:PS1}firstName:Martin Do you have any idea why the children query parser leads to an error and the parent query parser not? I am using Solr 5.2.0 (5.2.0 1683206 - anshumgupta - 2015-06-02 18:32:43). It is a cloud installation (using zookeeper) with 6 nodes (one shard per node).
