How to index 3-letter words?
By default the MySQL engine enables full-text search requests of 4-letter words or more. Hopefully, this can be changed.
According to MySQL documentation on Fine-Tuning MySQL Full-Text Search:
To rebuild indexes of tables used by YACS you can visit the Control Panel, and select the Optimization link.
" 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. "
