在Google Go中使用Olivere / Elastic更新ElasticSearch中的记录

Question

I am inserting a record in elastic search using go as stated here: https://github.com/olivere/elastic Now , if i have to partially update it(suppose if just one entry like 'name'), then i want to use UPDATE API. I cannot find any any documentation where they describe how to use this API/function in oilvere/elastic. I wonder if someone has used this before and could help me in this.

Answer 1

So, I finally got this thing working. Here is the code that i used to get it done.

update, err := client.Update().Index("test3").Type("user").Id("2").Doc(map[string]interface{}{"location": message}).Do()
fmt.Println("updated id: ", update.Id)

This is working fine for me.

I tried another approach to update it but it wasn't working. I am posting it here so one can view it and check. It was something like this.

update := client.Update().Index("test3").Type("user").Id("2").Script(elastic.NewScript("ctx._source.location = loc").Params(map[string]interface{}{"loc": message}).Lang("groovy"))
fmt.Println("updated id: ", update.Id)

Hope this helps someone!
