[jira] Commented: (LUCENE-1570) QueryParser.setAllowLeadingWildcard
could provide finer granularity

--------------------------------------
This is pretty easy to implement by overriding QueryParser.getWildcardQuery().

> It's great that Lucene now allows support for leading wildcards to be turned on. However, leading wildcard searches are more expensive, so it would be useful to be able to turn it on only for certain search fields. I'm specifically thinking of wiki searches where it may be too expensive to allow leading wildcards in the 'content:' field, but it would still be very useful to be able to selectively turn on support for 'path:' and perhaps other fields such as 'title:'. Would this be possible?
