/**
* When testing against a cluster requests can be routed to different nodes. This means after a
* save a document may not appear for all subsequent requests until an internal replication has
* finished between all the nodes. This method tries to find a document up to maxRetries times,
* with retries separated by 0.5 s. Retrying may route the request to a node that already has the
* document and the delay between retries also gives an opportunity for internal replication to
* complete between nodes increasing the chance of retrieving the document.
*
* <p>It should be noted that trying to read back a document immediately after writing to a
* cluster is not a best practice, but is needed in some test cases to reproduce, for example,
* conflict conditions. It is also worth noting that a document being returned from this method is
* not a guarantee that it has reached all nodes, only that it has reached a node that received
* one of the requests.
