Top-level parameters for constant_score [constant-score-top-level-params]

filter : (Required, query object) Filter query you wish to run. Any returned documents must match this query.

Filter queries do not calculate relevance scores. To speed up performance, {{es}} automatically caches frequently used filter queries.

boost : (Optional, float) Floating point number used as the constant relevance score for every document matching the filter query. Defaults to 1.0.
