Virginia,
I have finally found something that at least mostly works for searching. I tried to find all of the original story posts for Wrong Clark and after quite a bit trial and error I found the Search string of
+"Wrong Clark (" -"FDK - Wrong Clark" -"Re: Wrong Clark"
searching Subject only gets all of the Wrong Clark original posts plus one that I could not figure out how to get rid of.
Hope this might help some.
Mike
