[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=12782254#action_12782254 ]

--------------------------------------
Hi Mark,
Up to now, I was consuming ComplexPhraseQueryParser.java by means of copy paste into my source code, so I didn't notice.
Today I find out that ComplexPhraseQuery.java in Lucene 2.9.1 Misc has missed the non default field.patch.
It gives exception with author:"fred* smith" style queries.
I am writing a solr plugin to contribute for this query parser and Solr 1.4.0 directly depends on lucene-misc-2.9.1.jar.
Should I edit and include source code of ComplexPhraseQueryParser.java in my patch to solve this problem?
Or is there a more convenient way to do it?
Thank you for your consideration.

>
> 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...
