[jira] [Resolved] (LUCENE-1486) Wildcards, ORs etc inside Phrase
queries
[ https://issues.apache.org/jira/browse/LUCENE-1486?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erick Erickson resolved LUCENE-1486.
------------------------------------
Resolution: Fixed
The re-opens were from 2009. This stuff has been in Lucene for some time, and the comment "Reopening so we don't forget to do this one" makes me think this should have been closed a long time ago.
NOTE: we're also doing more work with this in the 4.8 time frame, thus it's getting some attention now.

> 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...
