How to Search the Internet Effectively
Search
Engines
Internet search sites can search enormous databases of Web pages, using titles, keywords or text
.
The challenge is to ask your question the right way, so that you don't end up overwhelmed with too many search results, underwhelmed with too few, or simply unable to locate the material that you need.
Slide8
Getting Started
Before doing a search, it's important to define your topic as completely and succinctly as possible
.
Write down exactly what information you're looking
for
why you're looking for
it
and what you're
not
looking for
.
This will help you to discover the best keywords for your search.
Slide9
Keywords
most
search engines work
best if you provide them with several keywords
.
So how do you determine which keywords will work best
?
Most users submit 1.5 keywords per search, which is not enough for an effective query - the recommended maximum is 6 to 8 carefully chosen words, preferably nouns and objects
.
Avoid verbs, and use modifiers only when they help to define your object more
precisely
Now you have your keywords. How do you enter them into the search engine?
Slide10
Use of Phrases
Your most powerful keyword combination is the phrase
.
Phrases are combinations of two or more words that must be found in the documents you're searching for in the EXACT order shown
.
To be exact you can use quotation marks
, Some searches provide specific options for phrases, while others don't allow them at all; but most will allow you to enter a phrase in quotation marks.
Slide11
Boolean Basics
"Boolean" searching (named after George Boole, the 19th-century mathematician who founded the field of symbolic logic) is a powerful technique that can narrow your search to a reasonable number of results, and increase the chance of those results being useful.
The three most commonly used Boolean commands (or "operators") are
AND, OR
and
AND
NOT
.
Slide12
AND
means "I want only documents that contain both/all words
.
For instance, the search "London" AND "Big Ben" AND "Buckingham Palace" AND "Trafalgar Square" would return only documents that contained all four keywords or phrases
.
AND is the most frequently used Boolean command.
Slide13
OR
means "I want documents that contain either word; I don't care which."
The query "London" OR "Big Ben" OR "Buckingham Palace" OR "Trafalgar Square" would return all documents that contained even one of these four keywords or phrases.
AND NOT
means "I want documents that contain this word, but not if the document also contains another word
.“
The query "London" AND "Big Ben" AND NOT "Buckingham Palace" would return documents that include London and Big Ben, but not those that also include Buckingham Palace.
Slide14
Formulating The Search Strategy
Planning the search
Regardless of the search tool being used, the development of an effective search strategy is essential if one hopes to obtain satisfactory results.
Formulation of the research question and its scope
Identification of important concepts within the question
Identification of search terms to describe those concepts
Slide15
Consideration of synonyms and variation of those terms
Preparation of the search logic
The
most productive searches are those where the information seeker has spent time working out a search strategy
before
going online.
Slide16
Work out your specific information need and identify the different major concepts and alternatives. For example, the topic
inorganic fertilizers
divides into two main concepts:
Inorganic fertilizers
Soil fertilization
Put ideas on paper in natural lang.
Examine each concept to find out as many synonyms and terms as you can think of
Slide17
