all_enriched

This index doesn't hold data from a particular data source. Instead, it's a dynamic merge of all kinds of contributions being tracked.

It is dynamic because the data is physically stored in the original indexes and is merged on the fly for each query.

It merges all kinds of contributions being tracked in the particular instance. Since the list of data sources tracked is configurable, your list of fields will differ from those of other customers.

Since each type of contribution has a different set of fields, the fields served by this index are not uniform for each element retrieved. You get a different set of fields depending on the data source each element comes from. Please refer to the data models of each data source (git commits, github issues, gitlab merge requests, jira tickets, etc) for more details.
