No, using the Search Multiple Indices method does not send multiple search requests to Algolia.
This method is designed to perform a single, batched request that queries multiple indices at the same time. Although you are retrieving results from several indices, the operation is processed internally as one API call, not multiple.
This is useful when you need to:
Display results from different indices in the same UI (e.g., products + blog content)
Perform multi-index queries with a single round trip to Algolia
