As is plainly stated in the plethora of "Lucene Query Syntax" pages on the web, Lucene does not support wildcard terms in phrase queries.
As to "my phrase"* returning every document, I can only guess you've set QueryParser.SetAllowLeadingWildcard(true) to cause "my phrase"* to parse to default_field:"my phrase" default_field:*. -----Original Message----- From: Kohlhepp, Justin W () [mailto:justin.kohlh...@thehartford.com] Sent: Thursday, July 12, 2012 10:52 AM To: lucene-net-user@lucene.apache.org Subject: RE: Expected behavior of phrase search with wildcard Yes.
