Executing a search

ElasticSearch was born as a search engine. Its main work is to process queries and give results. As we'll see in this recipe, search in ElasticSearch is not only limited to match some documents, but also to calculate additional information required to improve user experience.

The HTTP method used to execute a search is GET (but POST also works), the REST URLS are as follows:

http://<server>/_search
http://<server>/<index_name(s)>/_search
http://<server>/<index_name(s)>/<type_name(s)>/_search

Command

curl -XGET 'http://127.0.0.1:9200/test-index/test-type/_search' -d '${QUERY}'

{
    "query":{
        "match_all":{}
    }
}
