You can use a wildcard * to stand for any letter or letters. This is really helpful whenever you are not sure how to spell a word. (* is an asterisk and you type it by pressing and holding down the SHIFT key and tapping the number 8 once.)

Let's pretend that you're trying to remember a large word that was used in class today, and the only thing you can remember is that it starts with peri. No problem-- just type peri* in the search box!

The search engine will find all the documents that contain words that begin with peri, like perimeter, perihelion, periscope.

And another thing... Remember that all search engines are different. AltaVista (www.altavista.com) will let you use the wildcard symbol like this:

wom*n -- to find women and woman.

But Google (www.google.com) and Lycos (www.lycos.com) won't allow you to use the wildcard-at least not at the time of this writing. That could change, however, so always check the "Searching Tips" provided by each search engine.
