I am trying to setup ES for indexing document content for full text search. The document types that will be indexed are .docx and pdf.
Looks like ingest attachment plugin is to be used for this purpose and I've had a read of various articles including this post - How to specify file to Ingest Attachment
From what I understand, the plugin only takes bas64 encoded data for indexing and DOES NOT take an actual file "as-is"? I assumed that the fact that it uses Apache Tika meant that it has the capability to extract content from these doc types, so my question is, is there a way to actually send a file directly to this plugin or not?
