You are referring to fragmentation. In this case I'm pretty sure it's
just a matter of updating the indexes so that MySQL makes the correct
assumptions about the distribution of data. MySQL assumes data values
have an equal distribution in a database, updating the indexes will
force MySQL to u
when i reimport i usually drop all the indexes first anyway as it takes
forever i have found that a repair table quick usually helps after
reindexing too

I was under the impression that InnoDB tables took care of this for you.
You only need to be concerned if you add/delete repeatedly from anywhere
but the end rows of the table.
I'd like to know if I'm wrong about this.

i've tried simply re-creating the index as you suggested ... no luck.
here's a brief summary of my situation: i developed an application on one
server, after it was developed and ready to go live we started to move it
to another server. after moving it i noticed my search function wasn't
working
What about issueing first drop index, then add index? Should do
the job. Or repair table. What does check table or myisamchk say?
