I'm working on a portal that hosts multiple types of documentation (HTML, PDF, PPTx, DocX) and makes them all searchable in one place.
We could achieve this using the "standard" out of the box ElasticSearch and the Ingest Attachment plugin but I'm no data scientist and know very little about writing Elastic queries, so our search results are not great.
I've been recommended to use Enterprise App Search instead of trying tune my basic queries, but it would seem I can't use the ingest attachment plugin with it? As a result, I can't leverage simply sending base64 encoded content to the documents API and expect the content to be indexed.
Is there any way around this? Or would I not be able to use App Search for this??
