Ricardo Anguiano updated SOLR-13217:
------------------------------------
Reporter: Rahul Goswami (was: Rahul Goswami)
> collapse parser with /export request handler throws NPE
> -------------------------------------------------------
>
> Key: SOLR-13217
> URL: https://issues.apache.org/jira/browse/SOLR-13217
> Project: Solr
> Issue Type: Bug
> Affects Versions: 7.2.1
> Reporter: Rahul Goswami
> Priority: Major
>
> A NullPointerException is thrown when trying to use the /export handler with
> a search() streaming expression containing an fq which uses collapse parser.
> Below is the format of the complete query:
> [http://localhost:8983/solr/mycollection/stream/?expr=search(mycollection]
> ,sort="field1 asc,field2
> asc",fl="fileld1,field2,field3",qt="/export",q="*:*",fq="((field4:1) OR
> (field4:2))",fq="
> {!collapse field=id_field sort='field3 desc'}")
>
> I made sure that collapse parser here is the problem by removing all other
> filter queries and retaining only collapse filter query. The stacktrace is as
> below:
