When I literally search for nothing I get this error:
8: Undefined variable: fulltext_score_Capable_Words
/DCSearch.php
Line: 1674
Is this normal or could it be something I did?
fulltext_score_Capable_Words is not something I find in my clean SMF install...
Also, DCSearch isn't part of SMF. In Search.php there is a similar line:
$ignoreRequest = $searchAPI->indexedWordQuery($words, $search_data);
but, as you see, no $fulltext_score_Capable_Words variable is passed to that function...
What search-related MODs are you using?
My guess is...

Yep looks like that's the mod. I have the latest version too.
Searching for nothing is like dividing by zero. Your fourm will throw tantrums. :P
This MOD is for 1.1, should you be using it?
