Match All Query

A match all query returns all documents in the index, assigning each a _score of 1.0. This query is useful when retrieving all documents or when combined with other queries.

Example

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

query, err := effdsl.Define(
    effdsl.WithQuery(
        maq.MatchAllQuery(
            maq.WithBoost(1.2),
        ),
    ),
)

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

Parameters

• WithBoost (float64)
  (Optional, Functional option) Floating-point number used to decrease or increase the relevance scores of the query.

Match None Query

A match none query returns no documents. This query is useful when dynamically constructing queries and needing an explicit way to return no results.

Example

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

query, err := effdsl.Define(
    effdsl.WithQuery(
        mnq.MatchNoneQuery(),
    ),
)

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