TUTORIAL Google. A few years ago we were hearing about it for the first time, and now it’s so well used that we use the name as a verb – “Let me google that.“ But as powerful as it is, Google can often leave you – and your customers – overwhelmed by the amount of information it retrieves or wondering why a search has failed to retrieve any relevant results. The goal of this tutorial is to show you some of the techniques that you can use to improve the effectiveness of your Google searches. NOTE: To complete this tutorial, you will need to open Google (http://www.google.ca) in a browser window.
HOW GOOGLE WORKS
Understanding how Google works is a key part of effective searching. How Google Indexes the Web Google has a tool, Googlebot, which sends out requests for web pages. When a web page is sent back in response, Googlebot scans the page for hyperlinks and adds those links to a list that it will search at another time. Googlebot then sends the full text of the page to the indexer. The indexer stores the page in Google’s index (database). This index is organized alphabetically by search term – the words, numbers, and/or phrases that make up a search – and for each term, there is a list of web pages in which that term appears as well as information on exactly where in the page the search term is located. How Google Process Your Search When you enter search terms in the search box, Google looks through its index for pages that include your search terms. If it finds pages containing those terms, Google then considers the popularity of each of the pages, the position of the search terms in the pages, and the proximity of the terms within the pages. Google gives higher priority to pages that contain the search terms in the order specified in your search and where the search terms are found close to one another. So, now that you know how Google works, you’re ready to begin searching. Google Tutorial

Building an Effective Google Query Although Google will return results for most searches, there are a number of things that you can do to improve the effectiveness of your query.
1.
Select appropriate search terms
The search terms you enter can affect your search results. So, before you enter search terms in the Google search box, consider the question you're trying to answer. Think about the key concepts or ideas contained in the question. Consider the following query: I need articles about the use of biodiesel in the buses in the HRM. The key concepts would be biodiesel, buses, and HRM. Although you might think that “articles” is a key part of the question, this phrase probably won't appear in many pages. Including the phrase in the search will probably retrieve fewer results.
Did you know … • that a Google query can have up to 32 search terms? • that Google is case insensitive? You can use lowercase for all of the search terms in your query.
Also, notice that about and the haven't been included as search terms. These common words are considered stop words and are ignored by Google. Other stop words are: I, a, an, are, be, how, from, in, it, of, for, when, where, with, le, la, de.
Here are some guidelines for selecting search terms: •
Be specific - Avoid terms that are too vague and can have different meanings. for example, halifax citadel. Does this refer to Citadel Hill, the Citadel Halifax hotel, or the Halifax Citadel political riding?
•
Watch your spelling – a search with the term you’re will return different results than a search with the term your.
2.
Consider Word Order
Because of how Google works, the order in which you enter your search terms can affect your search results. Try the following: Carry out the following Google search: pop explosion. How many results were retrieved? ____________________ Now carry out this Google search: How many results were retrieved?
Google Tutorial
explosion pop. ____________________
Page 2 of 16
www.halifaxpubliclibraries.ca
Is there a difference in the number of results? Do some of the same pages appear in the results for both searches? You should notice a couple of things about the results retrieved by the two searches. First, the two searches retrieve slightly different sets of results. In other words, different pages appear in the results lists. Second, some pages appear in both sets of search results, but the order in which they appear is different. You can specify word order to Google by using double quotation marks (“ “). Known as phrase searching, this can be useful when you are searching for a quotation or a proper name (Paul Martin, Musquodoboit Harbour). A frequently used example of the impact of phrase searching is the well-known For example, if you search for to be or not to be, you get the following result
However, if you enclose the search terms in double quotation marks, you get
Carry out the following Google search: “pop explosion”. How many results were retrieved? ____________________
Exercises 1: Create an appropriate search (query) for the following questions. a.

Search: __________________________________________________________
Narrowing Your Search Often you'll carry out a search and Google will return an overwhelming number of results. How can anyone expect to review more than 1 million results? Even 200 results can be a lot of material to sift through. You can use a variety of techniques to reduce the number of results you get to something more manageable or to improve the likelihood that the results you get are going to be relevant.
a.
AND ( + )
When you enter a search query, Google retrieves for pages that contain all of the search terms. If you search for bicycle trails, Google will look for pages that contain the term bicycle and the term trails. This is called an implicit AND because you don't need to include AND between your search terms; Google automatically searches for pages containing all of them. The implicit AND can be useful when you're trying to improve the precision of your search. The more words you include in your search query, the more focussed your search. You will also notice that the number of results often decreases with addition of each new term. Try the following: Carry out the following Google search: bicycle trails. How many results were retrieved? ____________________ Now carry out this Google search: How many results were retrieved?
bicycle trails halifax. ____________________
Is there a difference in the number of results? You should notice that the number of results drops significantly when halifax is added to the search. Fewer pages contain bicycle and trails and Halifax.
Google Tutorial

www.halifaxpubliclibraries.ca
b.
NOT ( - )
Your search may retrieve a number of pages that are irrelevant to your topic. For example, a search for halifax may retrieve pages regarding Halifax, Nova Scotia and Halifax, England. If you're only interested in Halifax, Nova Scotia, you'll want to eliminate the other irrelevant results. This can be done using NOT which is indicated by the - (minus sign). Try the following: Carry out the following Google search: halifax. How many results were retrieved? ____________________ Now carry out this Google search: How many results were retrieved?
halifax -england. ____________________
Is there a difference in the number of results?
Notice that there is NO SPACE between the minus sign and the term being excluded.
You should notice that the number of results drops when you tell Google to exclude those pages that include the term england. While at first glance this may seem wonderful, there is a drawback.
Caveat Searcher (Searcher Beware!) Excluding a term can eliminate a lot of irrelevant pages from your search results, but it can also eliminate relevant results.
Halifax, Nova Scotia was named after an Englishman, George Montague-Dunk, 2nd Earl of Halifax. By telling Google not to include pages with the term england, you could eliminate pages discussing how the city got its name.
Exercises 2: Create an appropriate search (query) for each of the following questions. a.
I want information on the Halifax Citadel and I don’t want information on Citadel Halifax hotel.
Search: _________________________________________________________
b.
I need information about Tiger Williams the hockey player, not the golfer.
Search: __________________________________________________________

Expanding Your Search
a.
OR
Sometimes your search will not return as many results as you wanted. In this case, you can use the OR operator to increase the number of results. OR is especially useful when searching for synonyms or alternate forms of words. If you’re looking for information on car inspections, you could enter car inspections as your search query. You could expand your search by including synonyms for car and the OR operator. Try the following: Carry out the following Google search: car inspections. How many results were retrieved? ____________________ Now carry out this Google search: How many results were retrieved?
car OR vehicle OR automobile inspections. ____________________
Is there a significant difference in the number of results? The second search should produce a longer list of results because you’ve told Google that you will be happy with pages containing car vehicle automobile
and and and
inspections, inspections, or inspections.
Caveat Searcher The OR operator must be entered in ALL CAPS to distinguish it from the word or.
b.
Word Variations
When you submit a query, Google will find pages that contain your search terms. Google will also find pages that contain words that are similar to your search terms. For example, if you search for children public library, Google will also search for words like children’s, library’s, and libraries. This is called automatic stemming, that is, Google will search for the words that share the same stem or root.
Google Tutorial
Page 6 of 16
www.halifaxpubliclibraries.ca
But sometimes you don’t want Google to search for word variations. You just want Google to search for a term as you typed it. To indicate this, enter a + (plus sign) immediately in front of the term. (Don’t leave a space between the + and the search term!) Try the following:
Carry out the following Google search: children public library. How many results were retrieved? ____________________ Now carry out this Google search: How many results were retrieved?
children public +library. ____________________
Is there a significant difference in the number of results? You may see some reduction in the number of results because Google doesn’t have as many words to match.

c.
Synonym Operator ( ~ )
Another way to expand your search is to use the ~ (tilde). If you place it in front of a search term, Google will search for that term and its synonyms. The synonym operator works best if you use it with general terms or terms with lots of synonyms. Try the following: Carry out the following Google search: ~archives. What synonyms did Google search for? _____________________________________ _____________________________________
Here are some of the terms that Google will search for:

OTHER GOOGLE SEARCHES Google’s basic search is quite powerful, but there are other a number of features, advanced operators, and search services that can help you to find specific types of information.
a.
Features
Conversions If you need to convert a value from one type of unit to another (e.g., pounds to kilograms), you can use Google instead of your calculator or print conversion tables. You just specify the amount you want to convert and the units you want to convert it to. For example, if you want to convert 33 inches to centimetres, you could carry out this search
and get this result:
Maps If you need a map showing a particular location, try Google’s Maps. You can access the feature by clicking on the Maps link above the Google search box. To search for a specific address, enter the address (including the city or town) in the search box.
Google Tutorial

Google Services Google Scholar (http://scholar.google.com) Google Scholar is a service for searching for academic resources such as peer-reviewed papers, theses, and articles. Google Scholar can be searched using the same techniques you apply to Google. Some of the materials retrieved by Google Scholar are available in full text, but the results will often include links to articles in subscription databases. If you have the required username and password you can access the articles, otherwise you can try to obtain the material through an interlibrary loan service.

Google Services Google Scholar (http://scholar.google.com) Google Scholar is a service for searching for academic resources such as peer-reviewed papers, theses, and articles. Google Scholar can be searched using the same techniques you apply to Google. Some of the materials retrieved by Google Scholar are available in full text, but the results will often include links to articles in subscription databases. If you have the required username and password you can access the articles, otherwise you can try to obtain the material through an interlibrary loan service.
