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.
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!
If you're using github.com/olivere/elastic always check the unit tests. They not only serve as a safety net for changes but also illustrate how to use the library. E.g. update_test.go and update_integration_test.go come with a list of examples how to use the syntax explained in the documentation.
