Solr/Lucene QueryParser returns a TermQuery for "phrases" that end up
only as a single term. This could happen, for example, if it was
using Solr's "string" field type (which has effectively no analyzer).
I'd guess that you'd want to re-analyze TermQuery's? (though that
sound problematic for many cases) Or possibly use your own
SolrQueryParser subclass and override #getFieldQuery.

Hi,
I need to modify the query to search through all fields if no
explicit field
has been specified. I know there's the dismax handler but I'd like
to use
the standard query syntax.
I implemented that with my own QParserPlugin and QParser and for
simple term
queries it works great. I'm using the SolrQueryParser which I get
from the
schema to parse the query with an impossible field name as the
default field
and then I rewrite the query accordingly.
Unfortunately this doesn't work with phrase queries, the
SolrQueryParser
always returns a TermQuery instead of a phrase query.
What am I missing? Is this even a viable approach?
This is a code snippet from a test case (extending
AbstractSolrTestCase)
which I used to verify that it's not returning a PhraseQuery:
-----8<-----
SolrQueryParser parser =
h.getCore().getSchema().getSolrQueryParser(null);
Query q = parser.parse("baz \"foo bar\"");
assertTrue( q instanceof BooleanQuery );
BooleanQuery bq = (BooleanQuery)q;
BooleanClause[] cl = bq.getClauses();
assertEquals(2, cl.length);
//this assertion fails
assertTrue(cl[1].getQuery() instanceof PhraseQuery);
-----8<-----
I'm using solr 1.3, r685085.
TIA,
