Problem with SolrJ and Grouping
I found that SolrQuery doesn’t work with grouping.
I constructed SolrQuery this way:
solrQuery = constructFullSearchQuery(searchParams);
solrQuery.set("group", true);
solrQuery.set("group.field", "GeonameId");
Solr successfully handles request and writes about that in log:
INFO: [] webapp=/solr path=/select
params={start=1&q=*:*&timeAllowed=1500&group.field=GeonameId&group=true&wt=xml&rows=20&version=2.2}
hits=12099579 status=0 QTime=2968
The error occurs when SolrJ tries to parse
XMLResponseParser.processResponse (line 324), where builder stores
“</lst>”:
Object val = type.read( builder.toString().trim() );
if( val == null && type != KnownType.NULL) {
throw new XMLStreamException( "error reading value:"+type,
parser.getLocation() );
}
vals.add( val );
break;
The problem is - val is null. It happens because handler for the type
LST returns null(line 178 in the same file):
LST (false) { @Override public Object read( String txt ) { return null; } },
I don’t understand why it works this way. Xml which was returned by
Solr is valid.
If any I attached response xml to the letter. The error occures in the
line 3, column 14 661.
I use apache solr 3.3.0 and the same SolrJ.

The changes to that class were minor. There is only support for
parsing a grouped response. Check the QueryResponse class there is a
method getGroupResponse()
I ran into similar exceptions when creating the
QueryResponseTest#testGroupResponse test. The test use a xml response
from a file.

Martijn,
I can't find the fixed version.
I've got the last version of SolrJ but I see only minor changes in
XMLResponseParser.java. And it doesn't support grouping yet. I also
checked branch_3x, branch for 3.4.

Re: Problem with SolrJ and Grouping

Also the error you described when wt=xml and using SolrJ is also fixed
in 3.4 (and in trunk / branch3x).
You can wait for the 3.4 release of use a night 3x build.

Kirill,
Parsing the grouped result using SolrJ is not released yet I
think..its going to release with Solr 3.4.0.SolrJ client cannot parse
grouped and range facets results SOLR-2523.
see the release notes of Solr 3.4.0
