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
