I 100% agree that Funbags search still needs a lot of work, please do not think we are finished with it. Search is still in the beginning stages, but I do want to clarify as I think it might help:
From what I know, InnoDB with full text search was released in 2011 for MYSQL 5.6, however MYSQL 5.6 is still a release candidate as of today and not for production servers for live sites. 5.5 is the current release for MYSQL. See here:
http://dev.mysql.com/doc/ and
http://dev.mysql.com/ Oracle recently announced that it should ship in early 2013.
By the way, this stuff isn't my normal reading material, lol...
I appreciate any information or advice you provide as it allows us to make the site better, please always feel free to let me know your thoughts!
