FuzzyQuery doesnt support Stopwords
-----------------------------------

Key: LUCENE-2850
URL: https://issues.apache.org/jira/browse/LUCENE-2850
Project: Lucene - Java
Issue Type: Bug
Components: QueryParser
Affects Versions: 3.0.4
Environment: lucene version 3.x, hudson build #213 (16.12.2010 23:03:54)
solr version 3.x, hudson build #198 (16.12.2010 05:36:57)
Reporter: Peter


Stopword doesnt works if i use a fuzzy query.
Working Example:
-stopword: Gmbh
-request: {!edismax qf=name}xyz^100 Gmbh^100
-Parsed Query: +DisjunctionMaxQuery((name:xyz)^100.0)

Failure:
-stopword: Gmbh
-request: {!edismax qf=name}xyz~0.5^100 Gmbh~0.5^100
-Parsed Query: +((DisjunctionMaxQuery((name:xyz~0.5)^100.0) DisjunctionMaxQuery((name:Gmbh~0.5)^100.0))~2)

For me it seems to be a problem with getFuzzyQuery(field, termImage, fms) in QueryParser.java:1419.
The getFieldQuery method call returns null if i have a stopword. But getFuzzyQuery returns a DisjunctionMaxQuery.
But its my first project with lucene/solr... therefore my understanding can be wrong.

    -------------------------------------

    Hello, if you want to support stopwords for this type of query, then you can
    use a queryparser that passes them through the analyzer (like AnalyzingQueryParser).

    But in general, the basic queryparser does not analyze queries like fuzzy or wildcard or ranges.

    Resolution: Not A Problem

    Hi,
    it seems to be a problem in solr (i think so). I opened a solr issue (SOLR-2309).

    Regards,
