I found it really anoying that xoogle returns Google results in the middle of XOOPS search results. After all, I selected XOOPS search, not Google. Here's a little mod to remove Googles results from the XOOPS search.

Go to file; xoops_version.php
find line 24 // Search
$modversion['hasSearch'] = 1;

change it to // Search
$modversion['hasSearch'] = 0;

Now the module is not searchable by XOOPS and only returns XOOPS results on a XOOPS search. All other functions work as normal
