Hi All,
Please note that as per mysql manual the Full-text Search is not supported in innodb.
we are in the process of porting our application to innodb table types from existng table types of myisam and in our application we have made use of MySQL Full-text Search .
If any one of you know any work around for this problem ,please suggest us .

Thanking you all in advance:

You can always mixe innodb table and myisam on one table to use with Full text search

Thanks for the reply:
If I am not wrong in understanding your reply then you are saying that I can have tables of myisam and innodb in one database ,that is ok.
But my problem is that i have to change all the table from myisam to innodb to maintain refrential integrity between these table.

Or you can parse the strings with your application and store the words in the database. That's what we did for our app (and we needed to be portable across databases so we had no choice) and it works fine.
