GET /_search{ "query": { "ids" : { "type" : "my_type", "values" : ["1", "4", "100"] } }}Find by multiple IDs with JavaScript client for ElasticSearch:
client.search({ index: 'myindex', body: { query: { ids: { type: "my_type", values: ["1", "4", "100"] } } },}, (error, response) => { // handle response here});Refer to the official Elastic documentation for the Node client.
You also can use mget for this kind of query, like:
