ES: 6.1.1 NEST: 6.1 We have set our allowed script types to `stored` only. In reading [Allowed Script Contexts](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/modules-scripting-security.html#allowed-script-contexts-setting), it shows a couple of examples of available contexts but I've been unable to find a comprehensive list, let alone precise descriptions of each. So far, I have discovered by trial and error (literally, the error information that is returned from calls where my scripts are disallowed) what some of the other contexts are such as `filter` and `aggs` but I've also had to add `aggs_execute` which I can't differentiate from `aggs`. Why do I need both? Anyway, I'm assuming there's some good documentation somewhere but I haven't yet discovered it. Can anyone provide me some guidance here? ---

The documentation for this doesn't exist, yet (though, it's being worked on) as unfortunately scripts contexts have only begun to settle into some consistency. Here is a list of context names in the current version - though, it's not exactly a 1:1 mapping for script usage. This is something we hope to accomplish moving forward. analysis - AnalysisPredicateScript painless\_test - used for the Painless execute API interval - IntervalFilterScript aggs\_execute - used to execute different aggregations (though, this has been removed from the later versions) aggs - used for several different aggregations bucket\_aggregation - used for bucket aggregations aggregation\_selector - used for bucket aggregations field - used for script fields filter - used for several different types of filter scripts processor\_conditional - used for ingest condition scripts ingest - used for ingest processor scripts number\_sort - used for scripts that use score and return a numeric value score - used for score scripts aggs\_combine - metric aggregation combine script aggs\_init - metric aggregation init script aggs\_map - metric aggregration map script aggs\_reduce - metric aggregation reduce script script\_heuristic - signficant terms heuristic score script similarity - scripts that change how similarity for scoring is done similarityWeight - scripts that change the similarity weight for scoring string\_sort - sorting script that returns a string template - template script typically used by Mustache terms\_set - TermsSetQueryScript update\_script - scripts used to update documents moving-function - scripts used in moving function pipeline aggregations xpack\_template - template script for watcher watcher\_condition - watcher conditions scripts watcher\_transform - watcher transform scripts I fully appreciate this feature is nebulous and frustrating to use currently. ---

@Jack_Conradson Thank you very much! I appreciate you clearing things up as much as can be done now and I look forward to seeing it tightened up in the future. Can you further differentiate `aggs` and `aggs_execute`? I discovered that I had to use both (or possibly `aggs_execute` was the only one I **really** needed). ---

IIRC aggs\_execute was the name for aggregation "value scripts". These are aggs scripts which are run on each value of an aggregation, instead of each document. Doc values (the `doc` variable) are not available. Instead, `_value` provides the current value being aggregated on, and the final value is returned by the script. ---
