== Long-running searches
|
|
|
|
{es} generally allows you to quickly search across big amounts of data. There are
|
|
situations where a search executes on many many shards, possibly against
|
|
<<frozen-indices,frozen indices>> and spanning multiple
|
|
<<modules-remote-clusters,remote clusters>>, for which
|
|
results are not expected to be returned in milliseconds. When you need to
|
|
execute long-running searches, synchronously
|
|
waiting for its results to be returned is not ideal. Instead, Async search lets
|
|
you submit a search request that gets executed _asynchronously_,
|
|
monitor the progress of the request, and retrieve results at a later stage.
|
|
You can also retrieve partial results as they become available but
|
|
before the search has completed.
|
|
|
|
You can submit an async search request using the <<submit-async-search,submit
|
|
async search>> API. The <<get-async-search,get async search>> API allows you to
|
|
monitor the progress of an async search request and retrieve its results. An
|
|
ongoing async search can be deleted through the <<delete-async-search,delete
|
|
async search>> API.
