GET API

28 Jan 2019

Realtime

By default, the get API is realtime, and is not affected by the refresh rate of the index (when data will become visible for search). If a document has been updated but is not yet refreshed, the get API will issue a refresh call in-place to make the document visible. This will also make other documents changed since the last refresh visible. In order to disable realtime GET, one can set the realtimeparameter to false.

Refresh

The refresh parameter can be set to true in order to refresh the relevant shard before the get operation and make it searchable. Setting it to true should be done after careful thought and verification that this does not cause a heavy load on the system (and slows down indexing).
