SynchronizeKeepDatastore
When this parameter is set to True, a datastore file (.db) will remain on the disk after a synchronize action has been performed. When the synchronize action is next performed, this file will be checked by the connector so that it can index only documents that have changed since the last synchronize and can delete documents that have been deleted since the last synchronize.
If this parameter is set to False, the datastore file is deleted at the end of each synchronize action. The next synchronize action will fetch all documents and will not delete old documents.
