Comment: Searching less than 4 ?

This issue is related to MySQL default settings for full-text searching.

According to MySQL documentation on Fine-Tuning MySQL Full-Text Search

" For example, if you want three-character words to be searchable, you can set the ft_min_word_len variable by putting the following lines in an option file:

[mysqld]
ft_min_word_len=3

Then you must restart the server and rebuild your FULLTEXT indexes. "

To rebuild indexes you can visit the Control Panel, and select the Optimization link.
