fields - Fields to be used in the query.
use_dis_max - Boolean indicating to either create a dis_max query or a bool query. Defaults to true.
tie_breaker - Multiplier value to balance the scores between lower and higher scoring fields. Only applicable when use_dis_max is set to true. Defaults to 0.0.
The query accepts all the options that a regular match query accepts.
