Finding all PDF documents in Evernote

Here's a quick Evernote tip:

To find all notes that contain a PDF file within them, use the search query: resource:application/pdf.

This can be useful if you want to, for example, create a saved search of all your product manuals. Let's say you tag all your products with the tag called Products, and that for many of them you find a digital version of their manual online (which is virtually always in PDF format) and attach it to the note. You can create a saved search consisting of the query: Products resource:application/pdf and call it Product Manuals.

For more information about the resource filter, see the Evernote API documentation. Application/pdf is the mime type for PDFs. For a list of other mime types, see this excellent reference page.
