beagle indexes and cache

Hi

does beagle cleans up its indexes and textcaches now and then?
I mean it looks like old documents (now removed) still come up when 
searching...

is there a way to clean indexes and textcache, or should I simply remove 
these directories in the .beagle folder now and then?

thanks
	Lorenzo
