1. Speed More speed in inserts, deletes and selects.
2. Stoplist 1 stoplist for each index create fulltext index on x( y) stoplist 'mystop'
the stoplist could be divided in section like my.cfg: [STOPWORD] .... [VARIABLES] ft_min_word_len=3 .... [CLASSES] ... [SPECIAL CHARS] ...
The classes section defines word boundary; assigning chars or group of chars to one class (Alphanumeric, Word Break, punctuation, etc.). The parser uses this section to extract words to index. SPECIAL CHARS = replacement of some character ( ASCII > 128) to an equivalent 7bit character ( eg é=e --> index resumé as resume).
3. Proximity
4. TAGs Recognize tags to stop/restart index: inside the text I can insert tags to skip indexing a part of text (stop index, start index).
5. UDF or Filter Cascade UDF. The output of one function can be sent to input of another function. Every record can have a different filter. This solution allows to handle external documents( Text, Word, Excel, XML, PDF, etc) without storing their data in a table (just store path & type) crypt them (usefull in CD-ROM distribution). This filter can also fill other columns with data from the text.
These features with no great speed degrade can improve MySql and open new opportunity to MySql.
