[ https://issues.apache.org/jira/browse/LUCENE-1486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13200258#comment-13200258 ]
Mark Miller commented on LUCENE-1486:
-------------------------------------
bq. changing the visibility of "field" in the QueryParser base class to "protected".
This seems reasonable?

> 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...
