Search API

The search API allows you to execute a search query and get back search hits that match the query. The query can either be provided using a simple query string as a parameter, or using a request body.

Request Body Search

The search request can be executed with a search DSL, which includes the Query DSL, within its body. Here is an example:

GET /twitter/tweet/_search
{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
