Internet Search Strategies How are you searching now? • Google and Ask.com allow you to type natural language search strings, in other words, you type how you talk or ask questions. • Example: What is the population of China?
Problems with Natural Language Searches • Often natural language searches turn up too many or too few results. • So, what is the best way to search?
Boolean Operators • The most effective and efficient way for you to search is to develop a search string that includes one or more Boolean operators • What is a Boolean operator?
Boolean Operators • Boolean operators are words that include or remove possible search results. • The three Boolean operators are: AND OR NOT
AND Searches AND searches include results that have both search terms Example: tigers AND lions have results that are about both tigers and lions
OR Searches OR searches include results with either one or the other search term or both Example: tigers OR lions would include results that were either about lions or tigers or possibly both. You will find MORE results using an OR search.
Quotation Marks • Another good way to narrow your results is to put quotation marks around your search phrase • The results will be hits with that exact phrase • Example: “tiger life expectancy”
Why Evaluate Websites? • Anyone can publish on the Web • Many resources are not verified • No editors • Web often used to give a point of view • Market orientated • Mix of Entertainment, Information and advertising

Objectivity • Does the web page present information without bias? • Is the information correct and accurate in its representation? • Is the author fair and balanced or overly emotional and extreme? • Is the website trying to sell you something? • Check for affiliation (political groups, interest groups, hate groups)
Currency • Is the information up-to-date? • Is the date of publication available? • Is there sufficient information on the topic? • Are there broken links on the page?
Authority • What are the author’s qualifications for writing this web page? • Are the author’s name and credentials listed on the website? • Is there contact information on the site?
Presentation • Are there clear menus and navigation tools? • Does the page load quickly? • Is the layout logical? • Does the page load correctly? • Is the advertising unobtrusive?
