Google for Research

• Advanced Google Searching• Google Scholar• Google Books• Google U. S. Government Search

Objectives

You will learn to:• Simplify your searching,• Identify main concepts,• Search broadly to maximize relevant

results,• Target your search, and• Revise your search strategy.

Simplify Your Google Searching

• Type in lower case.•Google ignores capitalization in most cases.

• Leave out punctuation.•Some punctuation marks are actually search

commands that alter search results.• No need to connect terms with AND.

•Google always tries to find all search terms.• Enter search terms in the singular forms.

•Google should automatically search for all endings of words, both singular and plural.

Identify Main Concepts of Search Topic

• Take a moment to define the information you need to find.• I need recent, credible information about

outbreaks of avian flu.• Write down the two or more main aspects of

your topic.• Avian flu• Outbreaks

List Search Terms

• Make a list of search terms, including synonyms and related terms, for each concept. •Avian Flu

avian flu, bird flu, avian influenza, bird influenza, H5N1

•Outbreaks outbreak, incidence, incident, case, statistic

Tips for Searching Broadly

•We will cover the following tips for searching broadly to search more comprehensively on your topic:•Use OR to broaden search results,•Enclose each concept in parentheses, and•Use ~ to find similar words.

Use OR to Broaden Search

• Connecting keywords with OR retrieves results using the search terms on either side of the OR.

• Excellent strategy to retrieve results for synonyms or terms that are closely related in meaning.

• Brings together the results for both search terms into one big set.

• Use to search comprehensively on a topic.• OR must be capitalized.

Enclose Each Concept in Parentheses

• Use parentheses to enclose the search terms for each concept.• (avian OR bird OR H5N1) (flu OR influenza)

• Google searches for the terms within the parentheses first before combining with terms outside the parentheses.

Parentheses

Enclose Each Concept in Parentheses

• Use multiple levels of parentheses for more complex searches.

Use ~ to Find Similar Words

• Use the tilde symbol ~ to find similar words.• Google tries to retrieve results that include

words with similar meanings.• Put the tilde directly before the search term,

with no intervening space.•~avian

• Note: Since Google must cross-reference similar words, connecting keywords with OR is the most reliable method.

Target Your Search

• These tips will help you to target your search to retrieve the most relevant and useful search results:•Use “ ” for phrase searching,•Search for a range of numbers,•Search for certain types of Web pages,•Exclude terms from the search,•Retrieve documents with particular filetypes, and•Search for title words.

Use “ ” for Phrase Searching

• Surrounding phrases with quotation marks keeps the words together in this exact order.

• Particularly useful for names, concepts or titles involving multiple words.• “Avian influenza A (H5N1) infection in humans”

Use * to Fill in the Blank

• Use * to fill in the blank, if an intervening word is unknown.

Search for a Range of Numbers

• Google doesn’t provide a precise method for searching for dates of publication.

• To search for a range of numbers, connect the numbers with ..

Exclude Terms from Search

• Put the - immediately before the search term to exclude it.

• To find information about dolphins (the animal), but not football

Web Domains

• The domain at the end of a Web address indicates the type of organization or entity that published the Web page.•Commercial entity = .com•Non-Profit Organization = .org•Federal, state or local government = .gov•Educational institution = .edu

Limit to Particular Domains

• Limit the search to a particular type of Web site with command site: followed by the domain type.

• Sites published by government (.gov), educational (.edu) or non-profit organizations (.org) are generally good places to look for credible information.

Exclude Certain Domains

• Alternatively, exclude commercial sites using – immediately before the domain

• -site:com

Retrieve Documents with Certain Filetypes

• To limit search results to a certain filetype, place the command filetype immediately before the file extension, with no space.

• Commonly used and useful file extensions:• pdf: Portable Document Format, good for finding

handouts• xls: Excel, useful for finding data sets• jpg, gif, png, tif: Various filetypes for images• ppt: To find PowerPoint presentations.

Search for Words in Titles

• Use intitle: to require that the search term be in the title of the Web page.

Revise Your Search

• Different word orders retrieve different results.• Add additional search terms to your search

strategy to receive fewer and more specific results

• Try the Advanced Search Screen to the right of the Google search box.
