If you have a large forum, the search will take some time. The vB2 version of it is quite slow, being the loops that are processed. You might be better off waiting till vB3 RC is released, and I can re-open the vB3 version. (which works very fast)
As for the accuracy issue that you are experiencing partang.. I'm not sure about it. :ermm: It works fine with me.
Though, I just noticed a stupid mistake in the PHP file, and that is I have two values for my forums in this part:
PHP Code:
$discluded = ""; //Forums that are discluded
Make sure $discluded is instead says:
PHP Code:
$discluded = "0"; //Forums that are discluded
Unless you have already added forums there. There is no permissions check in this hack, so you have to manually add the forums you want not to be checked. I've updated the zip to remove this bug.
