  It does seem that what I want to do is possible.  So I'm just curious I
there is a way to access this functionality via Jena and it's free text
search feature.

voidsetLowercaseExpandedTerms(boolean lowercaseExpandedTerms)
Set to true to allow leading wildcard characters.
When set, * or ? are allowed as the first character of a PrefixQuery and
WildcardQuery. Note that this can produce very slow queries on big indexes.

Default: false.

I've just added that to jena-text in svn.




I can't say. I also would not try to, in this case. I expect performance
would be better using the filter.


A regex may well be better depending on the size and composition of the 
lucene index.
