Filter KQL field autocomplete suggestions

[micwiec]

Possibility to exclude fields from being autosuggested by KQL.

By example in Discovery tab or in Dashboard I would like to restrict number of autosuggested fields to avoid user confusion which field or subfield they should choose.

@lukasolson @mattkime could we use data view field filters for that?

Currently, the docs on the page where you configure these state the following:

Field filters can be used to exclude one or more fields when fetching a document. This happens when viewing a document in the Discover app, or with a table displaying results from a saved search in the Dashboard app. If you have documents with large or unimportant fields you may benefit from filtering those out at this lower level.

I guess we have to decide whether or not there are really two separate use cases here... To prevent the field from being fetched when fetching a document (e.g. for a very large field) or to prevent certain fields from showing up in the field selection entirely. They seem related. I'll note here that adding a field filter does not prevent it from showing up wherever there is a field selector (except in the case of Discover, since the field list is populated based on the fields inside of the document fetched).

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
