DESCRIPTION:
    This sample demonstrates how to get, create, update, or delete a Indexer.
USAGE:
    python sample_indexer_operations.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_SEARCH_SERVICE_ENDPOINT - the endpoint of your Azure Cognitive Search service
    2) AZURE_SEARCH_API_KEY - your search API key
