Full text search depends on the designer. Meaning, if you create your database as a relational database, you lose the full-text search in the case of innodb. Myisam allows you to fully search for text, but you are losing the true relational database. I would suggest abandoning sql db and use another db if possible. A good suggestion is CouchDB. Obviously, you will have to have a virtual or dedicated server to install CouchDB or any other db, even if you ask your host if they can install it for you. In most cases, the host will not just install the software just for you. There are free CouchDB sites. http://www.iriscouch.com I also understand the work that will be involved in switching everything to use alternative db. However, these are developer use cases.
