Search criteria item limit?

I’m using RT 2.0.15 on Rh8 linux (2.4.18-14bigmem
kernel), and have a question about the “search”
criteria when searching for tickets.
If I have up to 7 items in my criteria, the search is
performed correctly and results are returned. If I
add an 8th, the search criteria list will reflect this
8th item but nothing will be returned. The browser
doesn’t even try to perform the search.
If I add more than 8, they will not show up in the
criteria list at all.
Is 7 the max number of possible search criteria?
I found a way around the problem by using ‘isnt’
rather than ‘is’ when performing certain parts of my
search, but am still curious about the 7 limit.

Thanks!
