Aha! Okay, I figured out how to change/bypass the MySQL settings for Minimum Word Length and the Stopword lists.
If anyone else is interested, here's what you have to do:
NOTE: The following instructions are applicable for MySQL 4.0.18. I believe they are valid for 4.0.3 and above.
1. In your MySQL option file ("C:\Windows\My.ini", for example), under the central group category ( "[mysqld]", for example), add the following two items:
Code:
ft_min_word_len=2
ft_stopword_file=""
The first item sets the minimum word length to be indexed. In my example, I have it set to 2 characters.
The second item bypasses the MySQL Stopword list - which covers common words like "from", "and", etc...
Alternately, you can always edit the Stopword file directly. To do this, you need to find out what the default file/location is for your particular install (based on version, Platform, how it was installed, etc...)
Use and/or edit either of these two options to suit your needs.
2. After you have made the above changes, restart MySQL. (or, alternately, the entire server).
3. From your AdminCP, execute the following Queries:
REPAIR TABLE post QUICK
REPAIR TABLE thread QUICK
If you use Table Prefixes, edit "post" and "thread" accordingly.
After that, you should be done!
