==== Reindex and Update By Query
Before 5.0.0 `_reindex` and `_update_by_query` only retried bulk failures so
they used the following response format:
[source,js]
----------------------
{
...
"retries": 10
...
}
----------------------
Where `retries` counts the number of bulk retries. Now they retry on search
failures as well and use this response format:
[source,js]
----------------------
{
...
"retries": {
"bulk": 10,
"search": 1
}
...
}
----------------------
Where `bulk` counts the number of bulk retries and `search` counts the number
of search retries.
