  usage sample:

uipath = UiPathSDK()
index = uipath.context_grounding.get_or_create_index("test-radu", description="Test Radu Index", storage_bucket_name="radu-sb")
uipath.buckets.upload(
    bucket_name="radu-sb",
    blob_file_path="ion-creanga-povestea-lui-harap-alb.pdf",
    content_type="application/pdf",
    source_path="C:\\Users\\radu.mocanu\\Downloads\\ion-creanga-povestea-lui-harap-alb.pdf")
uipath.context_grounding.ingest_data(index)
no_of_retries = 5
results = []
while no_of_retries:
    try:
        results = uipath.context_grounding.search(
        "test-radu",
        query="Cine e Harap Alb?",
        number_of_results=5)
        break
    except IngestionInProgress as ex:
        print(ex)
        no_of_retries -= 1
        sleep(3)
print(results)
uipath.context_grounding.delete_index(index)
