Greets,
If you needed to know not just the total number of hits, but the
number of hits in each "category", how would you handle that?
For instance, a search for "egg" would have to produce the 20 most
relevant documents for "egg", but also a list like this:
Holiday & Seasonal / Easter 75
Books / Cooking 52
Miscellaneous 44
Kitchen Collectibles 43
Hobbies / Crafts 17
[...]
It seems to me that you'd have to retrieve each hit's stored fields
and examine the contents of a "category" field. That's a lot of
overhead. Is there another way?
Statistical sampling of results and estimation, that's what I use ...
for large result sets works reasonably well, for small result sets I
just pay the penalty of retrieving all docs.
Also, take a look at the following:
