marks around the phrase, like this Now, only pages that have all the words and in the exact order shown above will be listed The answers should be much more on target than with simple addition ④ Combining Symbols Once you've mastered adding, subtracting and multiplying, you can combine symbols to easily create targeted searches Weg or example, remember the person who wanted pages only about Star Treks original series? searched this way star trek-voyager-deep-space-nine-next -generation a better search might use subtraction and multiplication star trek"-voyager-"deep space nine"next generation ⑤ Wildcards(*) ou can search for plurals or variations of words using a wildcard character.

The format looks like this. ing* finds singing and sings theat* finds theater and theatre Some of the search engines offering wildcard search also support what is called"stemming. That means they will find terms like"singing"even if you only enter"sing. "This also means you may not need to use a wildcard symbol 2. Example (1)Google Google's advanced search page uses the allinurl command for finding URLs that contain described more on the Checking Your Listing page. However, it is the undocumented"inurl"command that you should use, if you want to find both web pages with words in the URL and within the pages themselves For example, let's say you want to find PDF files about mars exploration.

Here's both commands, combined mars exploration inurl: pd If you used the "allinurl"command rather than the inurl"command, this search wouldn,'t wo B e way, the"allinurl"command takes its name because when using it, you are requiring that aLL the words appear iN the URL. In contrast, the inurl command means that ANY of the words you specify should appear Google also has a command that lets you narrow your search to find documents in particular formats, such works better than forcing the URL command into this role. The command is filetype: and you follow it with the extension you want to search for. For instance california power crisis filetype: pdf brings back PDF files that contain the words"california power crisis. In contrast california power crisis filetype: asp brings back Microsoft Active Server Pages(ASP)files, while california power crisis filetype: html brings back ordinary HTML files that end in html, that contain the words. It will not bring back HTML files the end in htm, however. Technically, Google considers those to be a different file type, simply because the ending is different (2).
