Query DSL

In this manner, we need to provide a request body with the uri just like we have been using for Document APIs. We can rewrite our author search query as follows:

$ curl -XGET 'http://localhost:9200/library/book/_search?pretty' -d '{
 "query" : {
 "term" : {"author" : "gupta"}
 }
 }'

This query will return the same result. Whatever query parameters we defined using q=, we define them in term. To learn more about Query DSL, refer to https://www.elastic.co/guide/en/elasticsearch/reference/5.1/query-dsl.html.
