[jira] [Commented] (LUCENE-1486) Wildcards, ORs etc inside Phrase queries

    [ https://issues.apache.org/jira/browse/LUCENE-1486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13903081#comment-13903081 ] 

Nikhil Chhaochharia commented on LUCENE-1486:
---------------------------------------------

The patch posted by Ahmet Arslan on 8th Feb 2012 looks good to me. I have been using it in production for some time and did not find any issues.

I will request a committer to kindly look into this and help get this included into Solr 4.7.  If any further work is required, then I will be happy to give it a shot.

> 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...
