Hmm...this is a bit convoluted. You'd have to know the number of entries 
in advance, then make sure the entry cache size was configured to a 
larger number, then perform a search for all entries to force them into 
the cache, and finally read the count. Wouldn't it be easier to just use 
the search output to count the entries ? I suppose if you had a 
gazillion entries, so many that it would take a very long time to send 
them back to a client, then it might be worthwhile. You'd need to 
concoct a search that you knew would touch every entry but would not 
return any of them (a filter that is un-indexed and doesn't match any 
entry would do it).
