I'm new to Goleng and Elastic. I have a static query that I took out of the Kibana, now I want to use this query to build a dynamic query code according to the parameters that the customer will send

how i add or remove "event_state.status" according to user parameters. how i convert this json to map[string]interface {}. The client package i was use its https://github.com/elastic/go-elasticsearch

this is the json query :

You can store the query string in a raw string constant, the parts that you need to replace can be fitted with formatting directives such a %s, %d, %v.

Pass the raw string constant to fmt.Sprintf along with the variables in the correct order.

You might want to look at using the text/template module which is part of the go std library. https://pkg.go.dev/text/template

//The information you want to pass to your template
type Inventory struct {
    Material string
    Count    uint
}

var outputBuff bytes.Buffer

// define your template here 
queryTemplate := "{{.Count}} items are made of {{.Material}}"

queryParameters := Inventory{"wool", 17}

tmpl, err := template.New("test").Parse(queryTemplate)

if err != nil { panic(err) }

err = tmpl.Execute(&outputBuff, queryParameters)

if err != nil { panic(err) }

authoredQuery := outputBuff.String()
