I've been working with ElasticSearch for the last 6 months or so and have been very happy with the features and performance. However, I have run into a problem I'm not sure if ES supports. I have a web application in which users are creating multiple standing queries (sometimes relatively complicated). I've been converting the queries to named filters and running them with the appropriate ANDs and ORs to create the result set. I can tell which result belongs to which query/filter via the matched\_filters field. I would like to add in an ability to facet on the length of the matched\_filters array and provide how many times a result matched a query. I can do the calculation within code but it would probably be faster and easier within ES. Can it give me back that info? Thanks, Ken -- ---

Would Filter Facets[http://www.elasticsearch.org/guide/reference/api/search/facets/filter-facet.html](http://www.elasticsearch.org/guide/reference/api/search/facets/filter-facet.html)work for you?

Igor, Yes, they would and I've been using them for a variety of other tasks. However, I can't seem to get them to reference the generated matched\_filters field rather than \_source. I haven't had time to dive into the code so I wasn't sure if it was possible or not.

I don't think you can reference named filters from filter facets but you can simply repeat filters in the facets instead.
