In my GUI I want to show all the keys as suggestions. How can I get these keys from elasticsearch using (node js) elasticsearch npm

Hey,

you can use the [Get Mapping API](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-mapping.html) to get all your fields.

That is the Get mapping API, so you are using the correct endpoint already. I dont understand your question then? Where is your problem of using that API?
