From the Elasticsearch documentation:

If no fields are provided, the multi_match query defaults to the
`index.query.default_field` index settings, which in turn defaults to
`*`. `*` extracts all fields in the mapping that are eligible to term
queries and filters the metadata fields. All extracted fields are then
combined to build a query.
