QueryParser does not (currently) support SpanQuery's. PhraseQuery is
what you'll always get with double-quoted strings. However, you can
customize the behavior and get a SpanQuery instead by subclassing and
overriding getPhraseQuery. In fact, this is an example I wrote for
Lucene in Action.

hi all
i have a question regarding the QueryParser and Proximity Searches
I executed the following piece of code
String x = "\"jakarta apache\"~100";
QueryParser parser = new QueryParser("FULL_TEXT",new
StandardAnalyzer() );
parser.setOperator( QueryParser.DEFAULT_OPERATOR_AND );
Query query = parser.parse(x);
System.out.println(query.getClass()+" - "+query.toString());
IndexReader indexReader = IndexReader.open( new File(luceneroot)
);
query = query.rewrite(indexReader);
System.out.println(query.getClass()+" - "+query.toString());
in both System.out.println I get the following result
class org.apache.lucene.search.PhraseQuery - FULL_TEXT:"jakarta
apache"~100
is this correct, I was expecting to see a SpanQuery being formed at
the
second println statement
I have take this from the example in
http://jakarta.apache.org/lucene/docs/queryparsersyntax.html
If I remove the quotes I see a QueryParsing error which tell me that
the
Similarity should be between 0.0 and 1.0
which is as expected
please let me know if I missed something
Regards
Rupinder
