RE: Building a facet query in SolrJ

[Simon, Richard T]

I take it back. I didn't find it. I corrected my values and the facet queries 
still don't find what I want.

The values I'm looking for are URIs, so they look like: http://place.org/abc/def

I add the facet query like so:

query.addFacetQuery(MyField + ":" + "\"" + uri + "\"");


I print the query, just to see what it is:

Facet Query:  MyField:" : http://place.org/abc/def";

But when I examine queryResponse.getFacetFields, it's an empty list, if I do 
not set the facet field. If I set the facet field to MyField, then I get facets 
for ALL the values of MyField, not just the ones in the facet queries.

Can anyone help here?

Thanks.

Oops. I think I found it. My desiredFieldValues list has the wrong info. Knew 
there was something simple wrong.

Hi - I'm trying to do a (I think) simple facet query, but I'm not getting the 
results I expect. I have a field, MyField, and I want to get facets for 
specific values of that field. That is, I want a FacetField if MyField is 
"ABC", "DEF", etc. (a specific list of values), but not if MyField is any other 
value.

If I build my query like this:

SolrQuery query = new SolrQuery( luceneQueryStr );
      query.setStart( request.getStartIndex() );
      query.setRows( request.getMaxResults() );
      query.setFacet(true);
     query.setFacetMinCount(1);

      query.addFacetField(MYFIELD);

      for (String fieldValue : desiredFieldValues) {
           query.addFacetQuery(MYFIELD + ":" + fieldValue);
     }


queryResponse.getFacetFields returns facets for ALL values of MyField. I 
figured that was because setting the facet field with addFacetField caused Solr 
to examine all values. But, if I take out that line, then getFacetFields 
returns an empty list.

I'm sure I'm doing something simple wrong, but I'm out of ideas right now.
