Constant Score Query

A constant score query wraps a filter query and returns every matching document with a relevance score equal to the boost parameter value. This query type is useful when you want to apply a uniform score to all documents that match a specific filter query.

Example

import (
    es "github.com/elastic/go-elasticsearch/v8"
    "github.com/sdqri/effdsl/v2"
    csq "github.com/sdqri/effdsl/queries/constantscore"
    tq "github.com/sdqri/effdsl/queries/termquery"
)

query, err := effdsl.Define(
    effdsl.WithQuery(
        csq.ConstantScoreQuery(
            tq.TermQuery("user.id", "kimchy"),
            1.2),
    ),
)

res, err := es.Search(
    es.Search.WithBody(strings.NewReader(query)),
)

Parameters

• Filter (effdsl.Query)
  (Required, positional) The query object that documents must match. This is a required parameter.

• Boost (float64)
  (Required, positional) A floating-point number used as the constant relevance score for every document matching the filter query. This is a required parameter and defaults to 1.0 if not specified.
