- Search within a specific website (site:)
Google allows you to specify that your search results must come from a given website. For example, the query [ iraq site:nytimes.com ] will return pages about Iraq but only from nytimes.com. The simpler queries [ iraq nytimes.com ] or [ iraq New York Times ] will usually be just as good, though they might return results from other sites that mention the New York Times. You can also specify a whole class of sites, for example [ iraq site:.gov ] will return results only from a .gov domain and [ iraq site:.iq ] will return results only from Iraqi sites.

FTP Search Engines
- FTP -- FTP is built into your WWW browser so that it is now quite easy to transfer files down to your computer. Anonymous FTP allows you to use "anonymous" as the userid and your own e-mail address as your password. Once you have downloaded a file, you will probably need to uncompress or uncombine the file (using a File Compression utility: WinZip, 7-zip, etc.). File Transfer Protocol can also be used to upload files from your client machine to the FTP server machine.
- Although FTP (see ftp.htm) is still very useful and popular (for uploading and downloading files), FTP search engines (Archie) are almost never used any more.
- See also ftp.htm
- Archie: a User-index of anonymous FTP
- Archie by using Telnet: Login as "archie" and don't enter anything for a password. Try the Archie commands "?" "Help" "prog searchstring" "find" "whatis searchstring". Archie.McGill.ca

Telnet Search Engines
- Telnet -- Telnet allows you to run a program (such as an electronic library catalogue or pay-per-use database service) on another computer. Passwords are often required.
- You must make sure that a Telnet application has been set up in your Browser. You may be able to find Telnet, Trumptel, or WinTel already installed on your computer. If not, then you will have to download it and install it.
- Telnet is a protocol used to logon as a terminal to a remote system, such as Pegasus or LUIS. URLs (web addresses) that begin telnet:// or tn3270:// will try and start your telnet or tn3270 helper application.
