Editor's Notes
- Google U Rae Montgomery, University of Minnesota Extension Service, rae@umn.edu November 2004 1 and ½ hour hands-on workshop about Google’s Search Features. Participants will learn to search Google efficiently.
- Top Links Click on each top link as you explain it. Search the web The "I'm Feeling LuckyTM" button automatically takes you to the first web page returned for your query. Images: The most comprehensive image search on the web. Groups: (Usenet discussion archive) News: Search and browse 4,500 news sources updated continuously. Froogle: Search only for products that are for sale. 5 min hands on. Try it. Enter a search term and try it on a web, images, groups, news, and froogle searches.
- Demo these as you go through them. Than 5 minutes hands-on. Google supports several advanced operators, which are query words that have special meaning to Google. Typically these operators modify the search in some way, or even tell Google to do a totally different type of search. link: The query [link:] will list webpages that have links to the specified webpage. For instance, [link:www.google.com] will list webpages that have links pointing to the Google homepage. Note there can be no space between the "link:" and the web page url. The query [related:] will list web pages that are "similar" to a specified web page. For instance, [related:www.google.com] will list web pages that are similar to the Google homepage. Note there can be no space between the "related:" and the web page url. define: The query [define:] will provide a definition of the words you enter after it, gathered from various online sources. The definition will be for the entire phrase entered (i.e., it will include all the words in the exact order you typed them). stocks: If you begin a query with the [stocks:] operator, Google will treat the rest of the query terms as stock ticker symbols, and will link to a page showing stock information for those symbols. For instance, [stocks: intc yhoo] will show information about Intel and Yahoo. (Note you must type the ticker symbols, not the company name.) site: If you include [site:] in your query, Google will restrict the results to those websites in the given domain. For instance, [help site:www.google.com] will find pages about help within www.google.com. [help site:com] will find pages about help within .com urls. Note there can be no space between the "site:" and the domain. allintitle: If you start a query with [allintitle:], Google will restrict the results to those with all of the query words in the title. For instance, [allintitle: google search] will return only documents that have both "google" and "search" in the title.
- Demo a couple. 5 minutes hands-on.
- 5 minutes hands-on after slide to try their own searches. Finding information on the internet is easy, but finding what you’re looking for can sometimes be a challenge. All search engines offer a clickable Help area that offers tips on searching. Some tips that are especially helpful: Choose keywords carefully. WIDGET PARTS are the words we have chosen for this example. Google will search for websites that contain the words WIDGET and PARTS, but the words may not be together on the website. Put quotes around a phrase. In this example Google will find only sites that have “WIDGET PARTS” as a phrase. Add keywords to narrow the search. In this example we added GREEN to limit the search to sites that listed GREEN WIDGET PARTS. Exclude words. The minus sign (meaning NOT) in front of a word can be used to exclude sites with that word. For example, NOT CHINA By narrowing the search, we have fewer results to look at. But that can be better than looking at too many results!
