Don't forget the "in boolean mode" part. It will work a lot better:
SELECT * FROM $table WHERE MATCH (field1,field2,field3,field4) AGAINST ('red lion' IN BOOLEAN MODE);
http://www.mysql.com/doc/en/Fulltext_Search.html
Need more code? let me know. I've fallen in love with what in boolean mode has done for our search engine. I just wish RedHat and MySQL would get together to upgrade the rpms. MySQL 4 has been out for a long time, but only a very early version of MySQL 4.0.?? is available, unless you know lots about re-installing everything to get everything else to work. All it takes is one little old rpm to set things straight. Apprently there is some stupd licencing thing going on.
