Description

In the multimatch query, best_field, phrase, phrase_prefix, bool_prefix are supposed to max out of the score of the different fields. Right now quickwit combines their results.

Contributor guide

Research direction
Examine the multimatch query implementation in quickwit's elasticsearch API, specifically how scores from different fields are combined for best field, phrase, phrase prefix, and bool prefix types. Change from combining (sum/avg) to taking the maximum score.
