We recently purchased Ajax Pro and we’re trying to figure out if it’s possible to search the contents of a directory populated with PDF files using your search tool. Is it possible to meet with someone to see if this kind of configuration is possible?
I’m afraid that is not possible. The files need to be in the wordpress media library in order for the plugin to access them. The location of the download should not matter, as long as it is a media file in the media library and can be accessed by WordPress.
