FILE: sample_semantic_search_async.py
DESCRIPTION:
    This sample demonstrates how to use semantic search.
USAGE:
    python sample_semantic_search_async.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_INDEX_NAME - the name of your search index (e.g. "hotels-sample-index")
    3) AZURE_SEARCH_API_KEY - your search API key
