KQL + autocomplete in filter aggregation

[AlonaNadler]

Currently, filter aggregation only works with Lucene. Using KQL + autocomplete really makes it easier to create a query without the need to remember the exact field name and it assists with operators and values.
To expend the use of KQL and autocomplete beyond the search bar it will be helpful to support QKL+autocomlete in the visual editor filter aggregation and in TSVB filter aggregation
