Bug Keyword tagging not working properly

[highlander]

I just noticed that the tagging functionality isn't working properly. Here is a thread that I just created and was just tagged by DBSEO. Notice that almost none of the tags for the thread are present in the title or OP and yet there are things that should be tagged, specifically "ISTP" that are not showing up.

ISTP Careers

I have hotfixed this on your forum. This happened due to the fact that you use numbers as keywords, which confused the PHP function that was used to check for whether the keyword exists in the post or not.

I have switched to a stricter method of checking that works around this issue
