Disjunction Max Query

A disjunction max query (dis_max) is used to find documents that match multiple query clauses. The query returns documents that match any of the provided queries, and the relevance score is determined based on the best match. This query is useful for combining multiple queries into one and adjusting their scores with a tie-breaker.

Example

import (
    es "github.com/elastic/go-elasticsearch/v8"

    "github.com/sdqri/effdsl/v2"
    dmq "github.com/sdqri/effdsl/v2/queries/dismaxquery"
    tq "github.com/sdqri/effdsl/v2/queries/termquery"
)

query, err := effdsl.Define(
    effdsl.WithQuery(
        dmq.DisMaxQuery(
            []effdsl.QueryResult{
                tq.TermQuery("title", "Quick pets"),
                tq.TermQuery("body", "Quick pets"),
            },
            dmq.WithTieBreaker(0.7),
        ),
    ),
)

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

Parameters

• WithTieBreaker (float64)
  (Optional, Functional option) A floating-point number used to adjust the relevance scores when multiple queries match. This is an optional parameter.
