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
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)
