I'd like to amplify one of the comments below, in that something along the lines of index aliasing would be exceptionally useful, especially in cases when working with both rolling indexes ... and if y'all ever get around to fully supporting multiple indexes (https://feedback.azure.com/forums/263029-azure-search/suggestions/16700506-search-multiple-indexes-at-once)
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.
