You might also want to search the mail archive for "faceted search" and/or Categories. This topic has been discussed under that heading, I believe...

<java-user@lucene.apache.org> I have a Lucene related questions/problem. My search results can potentially get very large 200,000+. I want to categorize my results. So for example if I have an indexed field "type" that has such things as CDs, books, videos, power drills, or anything else in the world, I would want to display how many results are found for each unique "type". So I may get 200 CDs and 3000 books and so on. The brute-force way of doing that is traversing the returned documents/results and counting each unique type. Unfortunately this solution is too slow. I am having trouble figuring out a faster approach and was hoping someone can suggest one. Thank you for your time. Dima
