If the internal search mode is being used, there is a minimum word size of 3 chars and a stopwords list. The stopwords list is used as there are some words that will occur repeatedly and are not always going to be useful (such at the word "the") it also helps in situations where certain queries will require lots of processing (due to large set manipulations) and allow the returning of results faster.
To take a look/modify the stopwords list edit the file ../admin/GT/SQL/Search/Base/Common.pm at the top there will be a stopwords list. You can add remove items by editing the list and reindexing the database. Mysql fulltext search will be limited to 3 characters and will stop any keyword that can be found in more then 50% of the fulltext index.
