Trying to get a fix for "Fatal error: Allowed memory" error

[Vigile]

Many VB servers are having the issue of search results being to large for the PHP server to handle efficiently.

See these threads on VB.com:
http://www.vbulletin.com/forum/showt...Allowed+memory
http://www.vbulletin.com/forum/showt...Allowed+memory

After filling a support ticket, they told me to increase the amount of memory that PHP uses -- the problem is that though this would work, it will get VERY inefficient very quickly with each search on the forum using upto 32 or 64 MB of memory.

What I am looking for a way to limit how many threads or posts the VB search will look back into, so as to prevent this error from occuring. The Staff at VB.com seem unable to help me at all, instead saying:

"You can post that as a suggestion in the vB3 Suggestions forum, but for now this does require hacking the code."

Not a lot of help, is it?

Hopefully someone understands this issue better than I and can help a lot of people using VB out!
