Hi all, With the terms aggregation, you can use include/exclude to filter the buckets with regular expressions as described here: [http://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html](http://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html) . I am wondering whether it is possible to do the regex filtering before the buckets are returned? I have used the include/exclude option now, but I am getting incorrect total document counts.Could someone share an example query on how to do this?
