[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=12718281#action_12718281 ]
Mark Miller commented on LUCENE-1486:
-------------------------------------
What do you think about this for 2.9 Mark H?
bq. 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.
That leads me to think we might want to push to 3.0? Or have you moved beyond that with all of these updates?

> 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
> Priority: Minor
> Fix For: 2.9
>
> Attachments: ComplexPhraseQueryParser.java, 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...
