Subject Sort by relevance+distance
Date Sat, 17 Sep 2005 20:10:35 GMT
Hi,

I can sort the search results by distance now. But,
the relevance is lost.

I like to have the results sorted by relevance +
distance, i.e., relevance first; for results of
similar relevance, order by distance. How to do that?

Thanks a lot in advance!
-James
