Search Engine Strategies The 411 on Searching Effectively
But…. I know all about Google.  Why do I need a class in search strategies???
The Problem: Access to information is not a problem. You have access to information from around the world, and in every language, right at your desk .  The problem comes in finding relevant and useful information.
The Answer: Wise searching saves you time and effort. Knowing how to use search engines is an  essential  21 st  century skill.
THE Standard: Google The whole world has become  ‘ Google-ized’ Search engine of choice for many  Pros: Wide range of responses, sites from all over the world  Cons: Too many responses, not enough focus
You’re Kidding!!! Not at all. Although Google may be larger and more comprehensive than others, it isn’t always the best choice. The size and number of ‘hits’ sometimes makes it  difficult to use effectively.
Google Search: 53,600,000 hits

Another decision: Subject / Topic Keyword Full text What’s the difference?
Subject Directories If you need a lot of information on a rather broad topic, your best bet is not a search engine, but a Web directory like the  Open Directory Project ,   Google Directory  or   Yahoo.     A directory is a  subject-tree  style catalogue that organizes the Web into major topics such as Computers and Internet, Education, Government, Health, News, Reference etc.   Under each of these topics is a list of subtopics, and under each of those is another list, and another, and so on, moving from the more general to the more specific.

Keyword Search A  keyword  can simply be any word on a Web page.  Keywords would actually tell a user something about the subject and content of the Web page.  Search engines cannot return hits on keywords that mean the same, but are not actually entered in your  query . A query on heart disease would not return a document that used the word "cardiac" instead of "heart."
Full Text Indexing Full-text indexing systems generally pick up every word in the text except commonly occurring stop words such as "a," "an," "the," "is," "and," "or," and "www."  Some of the search engines discriminate upper case from lower case; others store all words without reference to capitalization.
Stop Words To be or not to be .  Some search engines choke because all the words in the phrase are  stop words -- i.e., unimportant words too short and too common to be considered relevant strings on which to search.    However, if you enclose the query in quotation marks, forcing the search engine to find the words, "to be or not to be" in that precise order, most search engines can  recognize the phrase as a famous quotation from  Hamlet .
“ Phrase searching” One of your best searching tools! Use only for legitimate phrases, names, titles Best example -- “vitamin A” “ John Quincy Adams” Titles “An Officer and a Gentleman” “ to be or not to be” Phrase searching is sometimes overused: not every group of words is a phrase Sometimes “ANDing” is a better strategy
How to structure a good query Brainstorm several  key words and phrases  — the ones you think would appear and wouldn’t appear in your dream document Anticipate synonyms and related words Mine your results!: be on the look out for better words and phrases as you search
More on the Query Focus on nouns (verbs are often vague, stop words, like articles—a, an, the—are ignored by most engines) Include  most important words and phrases first.
Wildcards and Stemming Google stems, it returns varied forms of words Many databases do not stem. Use an asterisk for various word forms adolesc*  child*  teen* BE CAREFUL when you stem :  cat*
The Boolean Machine http://kathyschrock.net/rbs3k/boolean/ Not And Or
Boolean Operator: AND Person or term must satisfy both/all attributes Examples:  Public AND Faculty: only faculty Public AND Students: only students  Public AND Faculty AND Students: faculty who are also students
Boolean Operator: NOT Person or term must NOT satisfy the attributes Examples:  Public NOT Employee: anyone who is NOT an employee Public AND Employee NOT Faculty: any employee that is NOT a faculty member
NOT as a refinement technique for problem words  eagles NOT Philadelphia “Martin Luther” NOT King
Boolean Operator: OR Person or term only needs to satisfy one of the attributes listed Examples:  Public AND Faculty OR employee: anyone who is a faculty member or an employee
When do you really need OR? OR is generally used for  synonyms or related words .

Better Search Options
Social Search Engines A  social search engine  is a type of  search engine  that determines the relevance of  search results  by considering the interactions or contributions of users. Example forms of user input include  social bookmarking  or direct interaction with the search results such as promoting or demoting results the user feels are more or less relevant to their query.  (source: Wikipedia)
Wink Social Search Engine Wink is a community-based  social search  engine. It provides  across social networks, and Web search based on user input. Wink is different from conventional  search engines  in that the relevant results are derived not just from machine algorithms, but directly from user input, such as  social bookmarking , voting up or down, or blocking results that are considered to be spam, thus allowing users to collectively create their own search engine.  www.wink.com

Meta-search Aggregators Dogpile www.dogpile.com   Searches Google, Yahoo, LookSmart, AskJeeves/Teoma, Google ADS, MSN search. Sites that have purchased ranking and inclusion are blended in. Accepts Boolean logic, especially in advanced search modes. Dogpile allows you to see each search engine's results separately in a  useful list for comparison .
Search Aggregator A  search aggregator  is a type of  metasearch engine  which gathers results from multiple search engines simultaneously through RSS search results.  Search aggregators are an increasingly popular way to take advantage of the power of multiple search engines with a flexibility not seen in traditional  metasearch engines .  (source: Wikipedia)

Meta Search In a meta-search engine, you submit keywords in its search box, and it transmits your search simultaneously to several individual search engines and their databases of web pages. Within a few seconds, you get back results from all the search engines queried.  http://www.lib.berkeley.edu/TeachingLib/Guides/Internet/MetaSearch.html
Some search engines also offer  subject / topic cues or clusters Check out this Clusty search…

Blog Search Engines Several blog search engines are used to search blog contents (also known as the  blogosphere ), such as  Bloglines ,  BlogScope , and  Technorati . Technorati, which is among the most popular blog search engines, provides current information on both popular searches and  tags  used to categorize blog postings. Research community is working on going beyond simple keyword search, by inventing news ways to navigate through huge amounts of information present in the  blogosphere , as demonstrated by projects like  BlogScope

Watch Out for: Sponsored Links
Watch Out For: Cookies A cookie is a small text file placed on your computer when you visit a website.  Not every website uses cookies, but you can expect to receive a cookie if you visit most of the popular websites on the internet, especially ones with advertising.  If you return to a website which previously gave you a cookie, that cookie is transmitted back to the website so that site operator knows you are visiting again.
Cookie Dough Many sites such as portals and news providers such as Yahoo.com allow users to set preferences, for example selecting which categories of news they would like to appear on their homepage.  These preferences are 'remembered' by means of a cookie.  Cookies are used to remember log-in names and passwords, so that users do not need to re-register every time they visit a site.   Many shopping sites such as Amazon.com allow users to create a "shopping cart" of items they wish to purchase.  The computer remembers your purchase list by means of a cookie placed on your computer.
Wikipedia and Citizendium For several years now, the online encyclopedia Wikipedia ( www.wikipedia.org ) has been drawing us into an interactive format for providing information. Citizendium is the new kid on the block.  To be fair, Wikipedia itself has evolved but there are inherent 'flaws', not the least being the relative anonymity of its authors. Citizendium takes on those flaws and ups the ante. I see Wikipedia as more the free-spirited, few rules hippie-type, and Citizendium being its more matured boomer type brother. Viva revolution!
