Searchable Attachments

You can attach a document to a knowledge article that can be found during a search. This document is enabled for a full text search. File formats supported are txt, doc, docx, xls, xlsx, and pdf. Other formats can be attached here, but will not be searchable.

Ensure that your Microsoft SQL server is enabled to search PDF files, if you plan to use this feature.

You can only attach one searchable document to a knowledge article at a time. If you attempt to upload another document, the original document is replaced by the new document.
