ES Query DSL

Structs and marshal-ers that help wrangle writing elastic search queries using the ES query DSL spec

Installation

go get github.com/mottaquikarim/esquerydsl

Usage

(You can copy paste the snippet below into playground and see for yourself)

package main

import (
	"encoding/json"
	"fmt"

	"github.com/mottaquikarim/esquerydsl"
)

func main() {
	body, _ := json.Marshal(esquerydsl.QueryDoc{
		Index: "some_index",
		Sort:  []map[string]string{map[string]string{"id": "asc"}},
		And: []esquerydsl.QueryItem{
			esquerydsl.QueryItem{
				Field: "some_index_id",
				Value: "some-long-key-id-value",
				Type:  esquerydsl.Match,
			},
		},
	})
	fmt.Println(string(body))
	// {"query":{"bool":{"must":[{"match":{"some_index_id":"some-long-key-id-value"}}]}},"sort":[{"id":"asc"}]}
}

(Please find additional examples in the unit tests)

MultiSearch Support

package main

import (
	"fmt"

	"github.com/mottaquikarim/esquerydsl"
)

func main() {
	doc, _ := esquerydsl.MultiSearchDoc([]esquerydsl.QueryDoc{
		esquerydsl.QueryDoc{
			Index: "index1",
			And: []esquerydsl.QueryItem{
				esquerydsl.QueryItem{
					Field: "user.id",
					Value: "kimchy!",
					Type:  esquerydsl.QueryString,
				},
			},
		},
		esquerydsl.QueryDoc{
			Index: "index2",
			And: []esquerydsl.QueryItem{
				esquerydsl.QueryItem{
					Field: "some_index_id",
					Value: "some-long-key-id-value",
					Type:  esquerydsl.Match,
				},
			},
		},
	})
	fmt.Println(doc)
	// OUTPUT:

	// {"index":"index1"}
	// {"query":{"bool":{"must":[{"query_string":{"analyze_wildcard":true,"fields":["user.id"],"query":"kimchy\\!"}}]}}}
	// {"index":"index2"}
	// {"query":{"bool":{"must":[{"match":{"some_index_id":"some-long-key-id-value"}}]}}}

	// ...
	// eventually, pass this in like so:

	// request := esapi.MsearchRequest{
	//	Body: strings.NewReader(doc),
	// }

}
