I am working on a product catalog whose search is powered by GSA. Each product is a single entry, but may have many associated documents. As I see there is only one content node allowed in the feed XML. is there a way to add multiple files to same record in the feed xml? Any suggestions?
Your best bet is going be when submitting each record to the feed, is to extract the content of associated documents and add as additional meta-data before sending to the feed.
Alternately, you can submit each record and each document, with some meta-data that references the record it's associated with. When returning search results, you could customize the front-end results to display related content (records or other attached documents).
