An index usually need to be reset because it has reached its error quota and been disabled. Resetting an index means forcing RavenDB to re-index all documents matched by the index definition, which can be a very lengthy process.
You can reset an index in one of the following ways:
Using the embedded API, by calling: DocumentDatabase.ResetIndex(indexName)
Using the HTTP API, by issuing a HTTP call to the index with RESET as the method name:
Deleting an index
You can delete an index by calling DocumentDatabase.DeleteIndex(indexName) from the Client API.
