---------------------------------------------------------------
Hi everyone,
I am using your ComplexPhraseQueryParser. I integrated it into Solr.
I am interested in it mainly because it supports OR operator and wildcards
inside proximity search.
Specifically : "(john johathon) smith"~10 and "j* smith"
They both work perfectly, thank you for your work.
I downloaded source code of it from
http://svn.apache.org/viewvc?view=rev&revision=791579
And then edited the code a little bit since I am using lucene 2.4.1:
I replaced those:
1-) TermRangeQuery to RangeQuery.
2-) getConstantScoreRewrite() to getUseOldRangeQuery();
3-) setConstantScoreRewrite(false); to setUseOldRangeQuery(true);
4-) On line 168 of ComplexPhraseQueryParser.java there are two semicolons ( ; ;
)
I am not sure what I did is the way to start using this query parser with
latest versions of lucene/solr.
If it is not can you suggest me better ways or where to get/download latest
source code of query parser.
I am having problems with multi-field searches.
Query "(john johathon) smith"~10 works on default field, e.g. text.
But when I want to run the same query on another field (other than default
field)
title:"(john johathon) smith"~10
it gives exception below:
Cannot have clause for field "text" nested in phrase for field "title"
When I ran the query distibuting field name to all terms it works:
title:"(title:john title:johathon) title:smith"~10
Is there an easy way to set field of all terms (without specifying)?
And about boosts of multi-field queries, is this query legal? (default operator
= OR, default field = text)
title:"(title:john title:johathon) title:smith"~10^1.5 OR "(john johathon)
smith"~10^3.0
Shortly I want to use this queryparser to query on multi-fields with different
boosts.
I am not sure if I am allowed to ask such question in here, if not please
accept my apologies.
Thank you for your consideration.

> Key: LUCENE-1486
> URL: https://issues.apache.org/jira/browse/LUCENE-1486
> Project: Lucene - Java
> Issue Type: Improvement
> Components: QueryParser
> Affects Versions: 2.4
> Reporter: Mark Harwood
> Assignee: Mark Harwood
> Priority: Minor
> Fix For: 2.9
>
> Attachments: ComplexPhraseQueryParser.java,
> junit_complex_phrase_qp_07_21_2009.patch,
> junit_complex_phrase_qp_07_22_2009.patch, LUCENE-1486.patch,

> TestComplexPhraseQuery.java
>
>
> An extension to the default QueryParser that overrides the parsing of
> PhraseQueries to allow more complex syntax e.g. wildcards in phrase queries.
> The implementation feels a little hacky - this is arguably better handled in
> QueryParser itself. This works as a proof of concept for much of the query
> parser syntax. Examples from the Junit test include:
> checkMatches("\"j* smyth~\"", "1,2"); //wildcards and fuzzies
> are OK in phrases
> checkMatches("\"(jo* -john) smith\"", "2"); // boolean logic
> works
> checkMatches("\"jo* smith\"~2", "1,2,3"); // position logic
> works.
>
> checkBadQuery("\"jo* id:1 smith\""); //mixing fields in a
> phrase is bad
> checkBadQuery("\"jo* \"smith\" \""); //phrases inside phrases
> is bad
> checkBadQuery("\"jo* [sma TO smZ]\" \""); //range queries
> inside phrases not supported
> Code plus Junit test to follow...
