Subject [jira] [Created] (SOLR-3744) Solr LuceneQParser only handles pure negative queries at the top-level query, but not within parenthesized sub-queries
Date Sun, 19 Aug 2012 21:41:37 GMT
Jack Krupansky created SOLR-3744:
------------------------------------

             Summary: Solr LuceneQParser only handles pure negative queries at the top-level
query, but not within parenthesized sub-queries
                 Key: SOLR-3744
                 URL: https://issues.apache.org/jira/browse/SOLR-3744
             Project: Solr
          Issue Type: Bug
          Components: query parsers
    Affects Versions: 4.0-BETA, 3.6.1
            Reporter: Jack Krupansky
             Fix For: 4.0, 3.6.2


The SolrQuerySyntax wiki says that pure negative queries are supported ("Pure negative queries
(all clauses prohibited) are allowed"), which is true at the top-level query, but not for
sub-queries enclosed within parentheses.

See:
http://wiki.apache.org/solr/SolrQuerySyntax

Some queries that will not evaluate properly:

test AND (-fox)
test (-fox)
test OR (abc OR (-fox))
test (-fox)

Sub-queries combined with the "AND" and "OR" keyword operators also fail to evaluate properly.
For example,

test OR -fox
-fox OR test

Note that all of these queries are supported properly by the edismax query parser.
