Elasticsearch REST APIElasticsearch supports HTTP request-response service, HTTP requests are broken by default with 9200, so the Curl command allows you to send an HTTP request and get the JSON return content. Common rest APIs include a few:Check ES cluster statuscurl http://localhost:9200/_cat/health?vCheck the status of the ES nodecurl http://localhost:9200/_cat/nodes?vQuerying all the Indexescurl http://localhost:9200/_cat/indices?vCreate an index

The Elasticsearch query is to construct the QueryBuilder object in the Java API by executing the query criteria in JSON format, Elasticsearch fully supports the QUERYDSL style query, The QueryBuilder build class is the Querybuilders,filter build class is filterbuilders. The following is an example of constructing QueryBuilder: Import static org.elasticsearch.inde

The few things you can do with the API are as follows: Check your cluster, node, and index health status and statistics Managing cluster, node, and index data and metadata Perform crud (Create, read, update, and delete) indexes and se
