I can't see search option in the demo. What if I sell 5000 docs? Is it possible to add some search fields to the document description. For example if I sell mp3s then need to add artist, album, year etc. all these fields needs to be searchable. Is it supported in this version?
There are a seach module for you to search for documents based on title, description and category of documents. If you are selling ebooks in PDF, there will also have a PDF indexer plugin which allow searching based on content of your ebooks .
