Boosting Query

A boosting query matches documents based on a positive query while reducing the relevance score of documents that also match a negative query. This type of query is useful for situations where you want to boost the relevance of documents that match a primary condition but penalize documents that match a secondary, less desired condition. The boosting query is constructed using a positive query, a negative query, and a negative boost factor.

Example

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

query, err := effdsl.Define(
    effdsl.WithQuery(
        bq.BoostingQuery(
            tq.TermQuery("text", "apple"),
            tq.TermQuery("text", "pie tart fruit crumble tree"),
            0.5),
    ), 
)

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