Comment 46 for bug 236947

Nate Irwin 3/12, sorry, I didn't notice your question when you posted it. If I don't get back to you within a few days, please remind me, either here or by email.

i30817, you can use "not" in Lucene queries--does that take care of what you're asking for? The one concern that I have is wanting to keep open the possibility of moving away from Lucene, so I don't want to promise long-term support for every weird feature of Lucene query syntax. But for now and the immediately foreseeable future, it should work, and any replacement should certainly support "not" in some form.
