4 DOING WEB QUERIES USING GOOGLE To enter a query into Google, just type in a few descriptive words and hit the 'Enter' key (or click on the Google Search button) for a list of relevant web pages. Since Google only returns web pages that contain all the words in your query, refining or narrowing your search is as simple as adding more words to the search terms you have already entered. Your new query will return a smaller subset of the pages Google found for your original "too broad" query. Reverse dictionary Choosing Keywords For best results, it's important to choose your keywords wisely. Keep these tips in mind: Try the obvious first. If you're looking for information on Picasso, enter "Picasso" rather than "painters". Use words likely to appear on a site with the information you want. "Luxury hotel dubuque" gets better results than"really nice places to spend the night in Dubuque" Make keywords as specific as possible. "Antique lead soldiers" gets more relevant results than "old metal toys". Automatic "and" Queries By default, Google only returns pages that include all of your search terms. There is no need to include "and" between terms. Keep in mind that the order in which the terms are typed will affect the search results. To restrict a search further, just include more terms. For example, to plan a vacation to Hawaii, simply type: 4

Automatic Exclusion of Common Words Google ignores common words and characters such as "where" and "how", as well as certain single digits and single letters, because they tend to slow down your

5 Automatic Exclusion of Common Words Google ignores common words and characters such as "where" and "how", as well as certain single digits and single letters, because they tend to slow down your search without improving the results. Google will indicate if a common word has been excluded by displaying details on the results page below the search box. If a common word is essential to getting the results you want, you can include it by putting a "+" sign in front of it. (Be sure to include a space before the "+" sign.) Another method for doing this is conducting a phrase search, which simply means putting quotation marks around two or more words. Common words in a phrase search (e.g., "where are you") are included in the search. For example, to search for Star Wars, Episode I, use: 5

6 Capitalization Google searches are NOT case sensitive. All letters, regardless of how you type them, will be understood as lower case. For example, searches for "george washington", "George Washington", and "george washington" will all return the same results. Word Variations (Stemming) Google now uses stemming technology. Thus, when appropriate, it will search not only for your search terms, but also for words that are similar to some or all of those terms. If you search for "pet lemur dietary needs", Google will also search for "pet lemur diet needs", and other related variations of your terms. Any variants of your terms that were searched for will be highlighted in the snippet of text accompanying each result. 6

7 Search By Category (Categories of Interest) The Google Web Directory (located at directory.google.com) is a good place to start if you're not exactly sure which search keywords to use. For example, searching for [ Saturn ] within the Science > Astronomy category of the Google Web Directory returns only pages about the planet Saturn, while searching for [ Saturn ] within the Automotive category returns only pages about Saturn cars. Searching within a category of interest allows you to quickly narrow in on only the most relevant pages to you. Getting Answers with Better Queries What makes a query good? It all depends on the question you want to answer. The typical search engine user s primary goal is usually not pages that contain some set of words. Rather, they are looking for the answer to a more general question not necessarily related to web pages. For example, they might be asking, What are some good recipes for apple pie? A good query is one whose resulting web pages are useful for answering the original question. A query that is not as good is one whose keywords match pages that are not relevant to the original question. In the pie recipe case, a simple and obvious query to try would be the following: However, when we tried this query, it returned about 370,000 pages, including many pages that have nothing to do with the food apple pie or how to make it but happen to have the words apple and pie on them. 7

8 Add keywords you know will be on relevant pages. The phrase query above is better than the original query, but it can be improved further. For instance, the results still include pages for companies selling apple pies, rather than offering recipes for them. One way to refine your query further is by adding keywords that you are certain will be on any page that is relevant to your original question about apple pie recipes. Sugar and cinnamon are almost always ingredients in an apple pie, and you always bake a pie, so this query is likely to return a smaller set of pages without excluding recipes interesting to you: Add keywords for a more specific answer. You might not be interested in sifting through over eight thousand pages of recipes, so, at this point, you might carefully reconsider your original question and see if you can make it more specific. For instance, you might not be such an expert cook, so to find recipes that are at your level, you might add the keyword, easy : 8

9 Add keywords you know will be on relevant pages. The phrase query above is better than the original query, but it can be improved further. For instance, the results still include pages for companies selling apple pies, rather than offering recipes for them. One way to refine your query further is by adding keywords that you are certain will be on any page that is relevant to your original question about apple pie recipes. Sugar and cinnamon are almost always ingredients in an apple pie, and you always bake a pie, so this query is likely to return a smaller set of pages without excluding recipes interesting to you: This query results in about 8,620 pages, most of which actually appear to be apple pie recipes. This query results in about 8,620 pages, most of which actually appear to be apple pie recipes. Add keywords for a more specific answer. You might not be interested in sifting through over eight thousand pages of recipes, so, at this point, you might carefully reconsider your original question and see if you can make it more specific.

10 Add keywords for a more specific answer. You might not be interested in sifting through over eight thousand pages of recipes, so, at this point, you might carefully reconsider your original question and see if you can make it more specific. For instance, you might not be such an expert cook, so to find recipes that are at your level, you might add the keyword, easy : This query results in 2,750 results, the vast majority of which are apple pie recipes that claim to be easy to prepare. Exclude keywords that you know do not appear on relevant pages. Many recipes for apple crisp list pre made apple pie filling as an ingredient, so the above query returns pages with such recipes. To exclude these pages from your results in Google, you can add the keyword crisp with a minus sign before it: Add keyword alternatives for word variations. Easy is only one word that describes recipes suitable for beginning cooks, so you might also want to allow pages with the word simple on them to be included in your results. Simply adding this keyword to your query, however, would require that both easy and simple be on the page. Using Google, you can indicate that one or the other (or both) are acceptable by putting OR (note capitalization) between the keywords: This further focuses your result set to 1,750 pages. Note that in this case, you are likely to increase the number of hits, but this might be useful if you believe you would otherwise exclude relevant pages. 10

11 Restrict your search to a particular domain. While going through some of the results from the above queries, you might notice that you are particularly interested in pages from the allrecipes.com web sites. You can restrict your Google search to pages on web servers in a particular domain by using site:domain to your query: For example, you might conduct a search for DVD player $ or 3..5 megapixel digital camera. Numrange can be used to set a range for everything from dates (Willie Mays ) to weights ( kg truck). This query finds all pages on servers within the allrecipes.com domain. (Note that there are no spaces around the colon between site and the domain name.) Doing Numrange searches: Numrange can be used to specify that results contain numbers in a range you set. You can conduct a numrange search by specifying two numbers, separated by two periods, with no spaces. Be sure to specify a unit of measure or some other indicator of what the number range represents. 11
