/**
* Find all documents where the value is matched in the fields. The type option
* allows you to specify the type of match, can be best_fields, most_fields,
* cross_fields, phrase, phrase_prefix.
*
* best_fields finds documents which match any field, but uses the _score
* from the best field.
*
* most_fields finds documents which match any field and combines the _score
* from each field.
*
* cross_fields treats fields with the same analyzer as though they were
* one big field. Looks for each word in any field.
*
* phrase runs a match_phrase query on each field and combines the _score
* from each field.
*
* phrase_prefix runs a match_phrase_prefix query on each field and combines
* the _score from each field.
*
