Can you refer to and filter on a script field in a query expression, after defining it?
elasticsearch
Solution
It's not possible for one simple reason: the script_fields are calculated during final stage of search (fetch phase) and only for the records that you retrieve (top 10 by default). The script filter is applied to all records that were not filtered out by preceding filters and it happens during query phase, which precedes the fetch phase. In other words, when filters are applied the script_fields don't exist yet.
Problem
I'm new to ElasticSearch and was wondering, once you define a script field with mvel syntax, can you subsequently filter on, or refer to it in the query body as if it was any other field? I can't find any examples of this while same time I don't see any mention of whether this is possible on the docs page http://www.elasticsearch.org/guide/reference/modules/scripting/ http://www.elasticsearch.org/guide/reference/api/search/script-fields/ The book ElasticSearch Server doesn't mention if this is possible or not either
