Hi Tod;
Thanks for your help.
I was able to do what you said but in a much uglier way using a Boolean
Query and adding Wildcard Queries.
The end result looks like this:
The query: +(type:138) +((-name:*tim* -name:*bill* -name:*harry*
+olfaithfull:stillhere))
But this one works as expected.
Thanks!
Luke
