Been playing around with the news 'facets search' and it works very well, but it's really slow for some particular applications. I've been trying to use it to display the most frequent authors of articles
I noticed this too, and have been thinking about ways to fix it. The root of the problem is that lucene, like all full-text search engines, uses inverted indicies. It's fast and easy to get all documents for a particular term, but getting all terms for a document documents is either not possible, or not fast (assuming many documents match a query). For cases like "author", if there is only one value per document, then a possible fix is to use the field cache. If there can be multiple occurrences, there doesn't seem to be a good way that preserves exact counts, except maybe if the number of documents matching a query is low. -Yonik
