I'm using full text search to pull rows.
I order the rows based on score (ORDER BY SCORE) , then of the top 20 rows (LIMIT 20), I want to rand (RAND) the result set.

So for any specific search term, I want to randomly show 5 of the top 20 results.

My workaround is code based- where I put the top 20 into an array then randomly select 5.

Is there sql way to do this?
