How can we improve Azure Search?

Search multiple indexes at once

The underlying elasticsearch technology supports making a single search query that searches and ranks results over multiple disparate indexes at once[1], but this functionality is not surfaced through the Azure Search APIs.

Adding this would allow a single search to span over indexes with different schemas combined in a single correctly ordered result set.

    Thank you for your feedback. We could support search across indexes in the same search service. Across different search services would be much harder. We’re considering this for a future release of Azure Search.

    Thanks,
