It's not going to speed everything up, just certain select statements.  And
quite honestly, it's going to speed up certain select statements that are
not really kosher.

For example, if your application is full of select statements like SELECT
FILE WITH @ID = "ABCDEF", then you should probably re-write the statement to
something like SELECT FILE "ABCDEF".  If you can't do that, because you
don't have the source, don't have the time or whatever, then creating the
index might help.

I first heard of this a few years ago and yes, it does work, but I've never
actually used it in a live application.  It's just not a real good use of an
index file.
