How to index files in elasticsearch?

Question

elasticsearch

Greetings.
Can you suggest the best way to proceed in this situation.

There is a small KB with articles. You can add n attachments to each article. This article and attachments need to be indexed and searched.

The article is clear. But with attachments, when there are more than one, it is not very clear how best to store them. In all manuals, as I understand it, through the ingest-attachment plugin, only one attachment can be added to one document.
Is there an option to add more? Or do they not give it that way, and do you need to create a separate document for each attachment? Or maybe there are some other options?

Answer 1

What about nested field type ?

Answer 2

It probably depends on the attachments - PDF can be parsed and searched for, pictures, etc. - No.

Answer 3

To index files, you can take Solr, running on the same engine.
