Hi, Now in master, and will be part of 0.9 is much more enhanced facets support. On top of the query facet that came with elasticsearch previous versions, there are now: - terms facet: The most frequent terms and their counts. [http://github.com/elasticsearch/elasticsearch/issues/207](http://github.com/elasticsearch/elasticsearch/issues/207) - statistical facet: Numeric field - get statistical information on it, including min, max, count, total, mean, std. [http://github.com/elasticsearch/elasticsearch/issues/212](http://github.com/elasticsearch/elasticsearch/issues/212) - histogram facet: my favorite - based on a certain field, break its values into buckets and provide aggregations within those facets (aggregations can be on the same field or on another field). [http://github.com/elasticsearch/elasticsearch/issues/215](http://github.com/elasticsearch/elasticsearch/issues/215), [http://github.com/elasticsearch/elasticsearch/issues/219](http://github.com/elasticsearch/elasticsearch/issues/219). On top of that, all facets can now accept filters that filter even more the "result set" they operate on. Also, there are new `and`, `or`, and `not` filters that are faster than the `bool` filter, see more here: > The global flag is applicable as well to all facets, controlling if they will be bounded by the executing query, or run globally (and bounded by the filters). When you have time, take it for a spin and tell me what you think. Other facets should be simple to implement (they must be "map reduce-able"), so if you have an idea for one, just shout. -shay.banon ---

Just built and tested this. Freaking awesome (the stats facet couldn't have come at a better time for me). Your pace of development has been amazing. I'm starting to think you're a machine 馃槈 -Eric On Thu, Jun 10, 2010 at 12:55 PM, Shay Banon [shay.banon@elasticsearch.com](mailto:shay.banon@elasticsearch.com)wrote: > Hi, > > Now in master, and will be part of 0.9 is much more enhanced facets > support.

Its just an extension to filters that provide that called bool filter, and I guess the idea was to create something similar to the boolean query. The other ones (and/or/not) are not part of Lucene or its modules. -shay.banon On Fri, Jun 11, 2010 at 12:02 PM, Clinton Gormley [clinton@iannounce.co.uk](mailto:clinton@iannounce.co.uk)wrote: > Heya > > > On top of that, all facets can now accept filters that filter even > > more the "result set" they operate on.

Very nice, I had a request for something like this glad to see it was added. 馃檪 On Fri, Jun 11, 2010 at 12:55 PM, Shay Banon [shay.banon@elasticsearch.com](mailto:shay.banon@elasticsearch.com)wrote: > Its just an extension to filters that provide that called bool filter, and > I guess the idea was to create something similar to the boolean query.
