[PHP] Mysql search query ignoring dots
Hi all, I have to perform a mysql query in a table with millions of records. I've full-text indexed my search field and I'm searching with MATCH AGAINST. But there is a problem. In this field there are company names that contain dots, for istance I've PO.SE. srl and I want to find it if the user search for: POSE or PO.SE or P.O.S.E. etc. I googled in the web but I don't find any solution. I don't want to add a new field with the cleaned version of my string because I would like to solve with the query and I prefer that the mysql table not become too big. But if I will not find a different solution, I will use this escamotage. I've find a post that is similar but the solution don't seem to solve my situation. You can see it at the url: http://forums.mysql.com/read.php?10,395557,395584#msg-395584 In my case replace(email, '.', '') = replace(theSearchValue, '.', ''); is indifferent and don't change my results. My query, searching POSE, is: select aziende.* from aziende where 10 AND (MATCH(aziende.ragione_sociale) AGAINST('+POSE' IN BOOLEAN MODE) OR (replace(aziende.ragione_sociale, '.', '') = replace('POSE', '.', '')) order by aziende.ragione_sociale limit 0, 10 The alternative choice could be REGEXP but I've red that it make my query slow in a table of millions of records and I don't know how to exclude dots in the regular expression. Can anyone help me? Thanks in advance. Barbara -- Barbara Picci Micro srl viale Marconi 222, 09131 Cagliari - tel.

As for ' a table of millions of records,' that sounds like questions for the DBA. Regards, Tommy -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It will probably save you a headache in the future and will be quicker than complicated queries. The list of possible ids can then be tested against the full table for any other criteria which if the table is indexed properly will be fast too. -- regards, Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
