The get request allows us to retrieve a document from an index by id.
In this example we are retrieving the document with id 'coldplay' from the bands index.
client.execute {
get("bands", "coldplay")
}You can specify a version, which means the GET will only succeed if the version matches.
client.execute {
get("bands", "coldplay").version(12)
}If the document exists with version 12 then this will return a result, otherwise it will return no results.
Other options are realtime, routing, preference, versionType, fetchSourceContext. For more details on what these do, consult the official elasticsearch documents here.
Get requests can be wrapped in a multiget query. Read more here.
