Docs around the `index` option were not very precise. The term "typical" was used without describing for which fields querying is still available when `index: false` is set. But more precise docs existed in the `doc_values` documentation found here for the index option: https://www.elastic.co/guide/en/elasticsearch/reference/current/doc-values.html This docs were mostly copied over.

=== `index`
|
|
|
|
The `index` option controls whether field values are indexed. It accepts `true`
|
|
or `false` and defaults to `true`.
|
|
|
|
Indexing a field creates data structures that enable the field to be queried
|
|
efficiently. <<number,Numeric types>>, <<date,date types>>,
|
|
the <<boolean,boolean type>>, <<ip,ip type>>, <<geo-point,geo_point type>> and the
|
|
<<keyword,keyword type>> can also be queried when they are not <<mapping-index,indexed>>
|
|
but only have doc values enabled. Queries on these fields are slow as a full scan
|
|
of the index has to be made. All other fields are not queryable.
