Wrapper query

A query that accepts any other query as base64 encoded string.

 GET /_search { "query": { "wrapper": { "query": "eyJ0ZXJtIiA6IHsgInVzZXIuaWQiIDogImtpbWNoeSIgfX0=" } } } 

1. Base64 encoded string: {"term" : { "user.id" : "kimchy" }}

This query is more useful in the context of Spring Data Elasticsearch. It’s the way a user can add custom queries when using Spring Data repositories. The user can add a @Query() annotation to a repository method. When such a method is called we do a parameter replacement in the query argument of the annotation and then send this as the query part of a search request.
