A searchable PDF is simply a PDF with multiple layers. The top layer is the original image as it was scanned in. Under that layer is a layer of text accurately positioned so that each word is directly behind the pixels that represent the word

A searchable PDF has following benefits:

   1. You can select the text, copy it to the clipboard, and then paste into a metadata collection form.
   2. You can highlight search hits.
   3. Search engines will be able to index the PDF and return it later as a search result.
