elasticsearch

This is an opinionated library for ElasticSearch in Go. Its opinions are:

  • Builders are bad: construct queries declaratively, using nested structures
  • Cleverness is bad: when in doubt, be explicit and dumb

Build Status

Usage

First, it helps to import the package with a short name (package alias).

import es "github.com/peterbourgon/elasticsearch"

Create a Cluster, which is an actively-managed handle to a set of nodes.

endpoints := []string{"http://host1:9200", "http://host2:9200"}
pingInterval, pingTimeout := 30*time.Second, 3*time.Second
c := es.NewCluster(endpoints, pingInterval, pingTimeout)

Construct queries declaratively, and fire them against the cluster.

q := es.QueryWrapper(
	es.TermQuery(es.TermQueryParams{
		Query: &es.Wrapper{
			Name:    "user",
			Wrapped: "kimchy",
		},
	}),
)

request := &es.SearchRequest{
	Params: es.SearchParams{
		Indices: []string{"twitter"},
		Types:   []string{"tweet"},
	},
	Query:   q,
}

response, err := c.Search(request)
if err != nil {
	// Fatal
}
fmt.Printf("got %d hit(s)", response.HitsWrapper.Total)
