I’m looking into app searches ability to search user favorites. It looks like the only supported way would be to pass the document ids in as a filter with the query (limit 1024 ids). I know I can do multiple queries to artificially extend that limit a bit up to 10x out of the box, but I wanted to check if there was another way that may be more performant?
I don’t have many documents, about a million, and most users will probably be fine with this limit, but we have over a million users. Any ideas are appreciated.
Plain Elasticsearch allows for term filters from another index in query but it doesn’t look like app search has this ability.
Almost forgot we do want to allow a user to create multiple favorites lists in the future.
