Hi, I'm playing with full text searches, that enables you do search very fast in a db, it replaces the where field like "%xx%" that is VERY slow on big tables (non indexed search). It's really a nice feature : immediate result for a search on a 400 000 lines table ! The same search with like %xx% is... more than 30s long (full parsing of the table) ! The problem is that i think this feature is not ANSI-92, so is mysql only compatible. Do you think we should ignore this feature, or become definetly mysql based product ? (unless it's ansi92, in this case, please say it !) documentation : http://www.mysql.com/doc/en/Fulltext_Search.html -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIBGB libre http://fr.koha.org)
