Re: MoreLikeThis throwing NPE

2007-09-10 Thread George L
Looks like the query field has to be stored for MLT.

It was failing when i had both query field and similarity fields unstored
before.

MLT is working fine with this configuration

query_field - indexed and stored
similarity_field - indexed, unstored and termvectors stored.

But why should the query field be stored?

It will be nice if http://wiki.apache.org/solr/FieldOptionsByUseCase is
updated.

Do you get the same error without solrj?

Can you run the same query with:
  http://localhost:8987/solr/select?q=id:11&mlt=true

(just to make sure we only need to look at the MLT code)

I have been trying the MLT Query using EmbeddedSolr and SolrJ clients, which
is resulting in NPE.

It looks like a problem as mentioned here
https://issues.apache.org/jira/browse/LUCENE-819
If that is the case,how to fix this?

The MLT field has been stored with termvectors.

The query i used and the exception is below.

In debug mode Lucene term.hascode() has been receiving some fields in the
index and breaking with the id field,
I was hoping to see the exception happening bcos of the mlt
fields/fieldValues. But it didn't.

Can somebody help me please, i have already spent a whole saturday night
with the trunk code ;-(

SolrQuery q = new SolrQuery();
q.setQuery( "id:11");
q.addFacetField("l");
q.setFacet(true);
q.setFacetMinCount(1);
q.setParam("mlt", true);
q.setParam("mlt.fl","field1");
q.setParam("mlt.minwl","1");
q.setParam("mlt.mintf","1");
q.setParam("mlt.mindf","1");
QueryResponse response = server.query( q );
