Null Pointer Exception on distributed search
Hi, We are facing NPE while using distributed search (Solr version 4.7.2) (using *shards* parameter in solr query) Exception Trace: ERROR - 2016-02-17 16:44:26.616; org.apache.solr.common.SolrException; null:java.lang.NullPointerException at org.apache.solr.response.XMLWriter.writeSolrDocument(XMLWriter.java:190) at org.apache.solr.response.TextResponseWriter.writeSolrDocumentList(TextResponseWriter.java:222) at org.apache.solr.response.TextResponseWriter.writeVal(TextResponseWriter.java:184) at org.apache.solr.response.XMLWriter.writeNamedList(XMLWriter.java:227) at org.apache.solr.response.TextResponseWriter.writeVal(TextResponseWriter.java:188) at org.apache.solr.response.XMLWriter.writeArray(XMLWriter.java:273) at org.apache.solr.response.TextResponseWriter.writeVal(TextResponseWriter.java:190) at org.apache.solr.response.XMLWriter.writeNamedList(XMLWriter.java:227) at org.apache.solr.response.TextResponseWriter.writeVal(TextResponseWriter.java:188) at org.apache.solr.response.XMLWriter.writeNamedList(XMLWriter.java:227) at org.apache.solr.response.TextResponseWriter.writeVal(TextResponseWriter.java:188) at org.apache.solr.response.XMLWriter.writeResponse(XMLWriter.java:111) at org.apache.solr.response.XMLResponseWriter.write(XMLResponseWriter.java:40) at org.apache.solr.servlet.SolrDispatchFilter.writeResponse(SolrDispatchFilter.java:756) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:428) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:205) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:220) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:122) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:171) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:950) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:116) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:408) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1040) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:607) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:314) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) Can somebody help us in finding the root cause of this exception?

Remove all parent docs having specific child doc
Hi,
I want to remove all the parent docs having a specific child doc. Eg.
docEmployee1
doc
fieldDept1/field
/doc
doc
fieldDept2/field
/doc
/doc
docEmployee2
doc
fieldDept2/field
/doc
doc
fieldDept3/field
/doc
/doc
Query: Remove all employees which lie in Dept1
Response should be: Employee2 *only*
Problem: *NOT operator is not being supported* in block join query parser.
*q = {!parent which=employee:*}*:* -department:Dept1 *- results Employee1,
Employee2
*q= - {!parent which=employee:*} department:Dept1 *- it does not work with
block join query parser.
Please suggest as to how I filter those employees which lie in Dept1 using
block join or any other query parser?
Thanks,
Lokesh
Re: Delete By query on a multi-value field
Hi Jean, Please see the issues https://issues.apache.org/jira/browse/SOLR-3862 https://issues.apache.org/jira/browse/SOLR-5992 Both of them are resolved. The *remove *clause (atomic update) has been added to 4.9.0 release. Haven't checked it though.

Lets say I have three documents A,B and C with field XYZ set to 1,2,3, 2,3,4 and 1. I'd like to remove anything that has the value '1' in the field XYZ. That is I want to remove the value '1' from the field, deleting the document only if '1' is the only value present. Deleting documents such as C (single value) is easy with a Delete by query through the update handler but what about document A? Thanks for any hint
