Please do not suggest search engines which only offer document/PDF search as one option. Instead, suggest it to the category on which it is focused and mention the document/PDF search option in the description, if relevant.This category contains search engines that look for documents stored as separate files on the World Wide Web. The most common format is PDF, but Word, Excel, and Powerpoint documents are also common and even plain text or rich text files can be included.
You may submit sites which also search for torrent files, if the emphasis is on file hosting services.The sites in this category are search engines which search the content of file hosting services like Fileserve, Filesonic, Megaupload, RapidShare.
Sites searching for torrent files should go to Computers/Internet/File_Sharing/BitTorrent/Torrent_Directories_and_Trackers/
