I once got this answer to a similar question on another group. http://www.mail-archive.com/[EMAIL PROTECTED]/msg00280.html Bernhard - Original Message - From: Nick Arnett [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, March 27, 2003 8:59 PM Subject: Fulltext search -- no wildcards in phrases? It appears to me that fulltext phrase searches cannot include wildcards. For example, I would expect app* serv* to match application server, application services, etc. But it returns no results, so I'm having to run each variation separately. Can anyone confirm that wildcards, indeed, can't be used in phrase searches. I'm doing these in Boolean mode because I need exact counts of occurrences.

Yes, phrase search currently doesn't work with operators.
