/**
 * Represents Elasticsearch "multi_match" query.
 *
 * @link https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html
 *
 * Allows `$fields` to be an empty array to represent 'no fields'. 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.
