----------------------------------
Summary: NullPointerException when run collapse filter
Key: SOLR-10885
URL: https://issues.apache.org/jira/browse/SOLR-10885
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: search
Affects Versions: 6.4.1
Reporter: jefferyyuan
Priority: Critical
Solr collapse is a great function to collapse data that is related so we only
show one in search result.
Just found one issue related with it - It throw NullPointerException in some
cases.
To reproduce it, first ingest some data - AND commit multiple times.
1. When there is no data that matches the query:
http://localhost:8983/solr/thecollection/select?defType=edismax&q=non-existType:*&fq={!collapse
field=seriesId nullPolicy=expand}&fq={!collapse field=programId
nullPolicy=expand}
- But the problem only happens if I use both collapse fqs, if I just use one of
them, it would be fine.
2. When the data that matches the query doesn't have the collapse fields
- channel data doesn't have seriesId or programId
http://localhost:8983/solr/thecollection/select?defType=edismax&q=docType:channel&fq={!collapse
field=seriesId nullPolicy=expand}&fq={!collapse field=programId
nullPolicy=expand}
- But the problem only happens if I use both collapse fqs, if I just use one of
them, it would be fine.

int nextDocBase = currentContext + 1 < this.contexts.length ?
this.contexts[(currentContext + 1)].docBase : this.maxDoc; - 617 from solr
6.4.1 CollapsingQParserPlugin.java
Seems related with https://issues.apache.org/jira/browse/SOLR-8807
- But SOLR-8807 only fixes issue related with spell checker.
I may test this with latest solr 6.6.0 when I have time.
