MySQL cardinality

MySQL cardinality

am 11.10.2007 11:07:58 von UKuser

I'm getting a Cardinality of 1 on all FULLTEXT indexes I create even
though I know there are hundreds of unique values. An explain is also
returning only 1 row which should be many many more as well.

Is this normal, and why might it be happening?

Now, Jerry, etc. THIS poster has put up a pure SQL question.

UKuser, this is a php group, not a sql or mysql group.
