Just realized I forgot to reply-all, response copied verbatim:
An extrator is meant to take some data and extract it's constituent
field-value pairs. If a field cannot be determined for a given value
then the default field should be used. For example, when indexing
`text/plain` there is no explicit field, it's just a bunch of text, so
the `default_field` specified in the schema is used. By default the
`default_field` is `value`.
It's also worth noting that if a field is not specified in a query the
default field is assumed.
Does this answer your question?
