Allows searching on number field types (long, short, int, float, double, byte, half_float) when those fields are not indexed (index: false) but just doc values are enabled. This enables searches on archive data, which has access to doc values but not index structures. When combined with searchable snapshots, it allows downloading only data for a given (doc value) field to quickly filter down to a select set of documents. Note to reviewers: I have split isSearchable into two separate methods isIndexed and isSearchable on MappedFieldType. The former one is about whether actual indexing data structures have been used (postings or points), and the latter one on whether you can run queries on the given field (e.g. used by field caps). For number field types, queries are now allowed whenever points are available or when doc values are available (i.e. searchability is expanded). Relates #81210 and #52728

=== `index`

The `index` option controls whether field values are indexed. It accepts `true`
|
|
or `false` and defaults to `true`. Fields that are not indexed are typically
|
|
not queryable.
