NullPointerException for more like this request handler via SolrJ if the
document does not exist
------------------------------------------------------------------------------------------------
Key: SOLR-2005
URL: https://issues.apache.org/jira/browse/SOLR-2005
Project: Solr
Issue Type: Bug
Components: clients - java, MoreLikeThis
Affects Versions: 1.4
Environment: jdk1.6
Reporter: Peter Karich
If I query solr with the following (via SolrJ):
q=myUniqueKey%3AsomeValueWhichDoesNotExist&qt=%2Fmlt&mlt.fl=myMLTField&mlt.minwl=2&mlt.mindf=1&mlt.match.include=false&facet=true&facet.sort=count&facet.mincount=1&facet.limit=10&facet.field=differentFacetField&start=0&rows=10
I get:
org.apache.solr.client.solrj.SolrServerException: Error executing query
at
org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:95)
at org.apache.solr.client.solrj.SolrServer.query(SolrServer.java:118)
Caused by: java.lang.NullPointerException
at
org.apache.solr.client.solrj.response.QueryResponse.extractFacetInfo(QueryResponse.java:180)

org.apache.solr.client.solrj.response.QueryResponse.setResponse(QueryResponse.java:103)
at
org.apache.solr.client.solrj.response.QueryResponse.<init>(QueryResponse.java:80)
at
org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:89)
The xml response of the url is empty and so the info variable at line
NamedList<Integer> fq = (NamedList<Integer>) info.get( "facet_queries" );
(QueryResponse) is null. Maybe all variables at QueryResponse.setResponse
should be checked against null? Sth. like
val = res.getVal( i );
if(val == null) continue;
?
