wildcards in phrase searches

[Le...@emc.com]

Is it possible to have wildcards in a phrase search? For example, if my
object is indexed with a phrase "benchmark properties", is there a way to
specify a phrase search that uses wildcards, such as "benchmar* properties"
or "benchmark pro*"? I have tried using WildcardQuery, but it doesnt seem to
work with phrases, only single terms. Using the QueryParser doesnt seem to
work either, and ive tried it with the StandardAnalyzer and KeywordAnalyzer.
Perhaps there is something simple Im missing here. Has anyone gotten this to
work?
 
Thanks in advance,
-G

It's a fair bit trickier than using any of the stock core classes  
like that.  But it can be done, using SpanNearQuery nested with  
SpanRegexQuery's for the wildcarded parts in the contrib code (note,  
this uses regex syntax, not WildcardQuery syntax), along with  
SpanTermQuery's for the non-wildcarded parts.
