Sort by date, filter by score?

[Shawn Heisey]

 I have had a request from our development team.  I did some searching 
and could not find an answer.

They want to sort by a date field but filter out all results below a 
minimum relevancy score.  Is this possible?  I suspect that our only 
option will be to do the search sorted by relevancy and then sort them 
ourselves.

Thanks,
Shawn
