I assume you reindexed everything? Anyway, the size of indexed fields generally grows sub-linearly (as opposed to stored fields which is exactly linear). But if it really barely grew at all, this could point to other parts of the index taking up much more space than you realize. If you could do an "ls -l" of your index directory, we might be able to see what parts of the index are using up the most space. -Yonik http://lucidimagination.com
