Wildcard Query

A wildcard query returns documents that contain terms matching a wildcard pattern.

Example

import (
    es "github.com/elastic/go-elasticsearch/v8"
    "github.com/sdqri/effdsl/v2"
    wq "github.com/sdqri/effdsl/queries/wildcardquery"
)

query, err := effdsl.Define(
    effdsl.WithQuery(
        wq.WildcardQuery(
            "user.id",
            "ki*y",
            wq.WithBoost(1.0),
            wq.WithRewrite(wcq.ConstantScoreBlended),
        ),
    ),
)

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