Deleting index

Was able to run the examples, very neat. Also figured out how to query a field without a boolean constraint, and how to do a disjunctive query using should.

When I go to delete the index, the systems takes awhile and then returns with an error:

{"statusCode":502,"error":"Bad Gateway","message":"getaddrinfo ENOTFOUND opensearch-node2 opensearch-node2:9200"}
