Lucene partial text search
Looking at the couch docs for lucene, they all reference FullText
searching.
I've done the simple example from the wiki and can get the search to
work if I put all the text in the field in the q="..." search.
Is it possible to do partial text searches? Like all the records that
contain "abc" in the field? Like a q="*abc*" wildcard query?
I see where the lucene documentation shows lots of capabilities, but
wonder if these are available/accessible in couch.
Thanks
Mike

can u use the fuzzy search(abc~) which will match against edit distance?

Yes but no */? as first char.
So how would you search for any field that contains "abc"?
Can't do q="*abc*".
