In many lengthy documents, just using the operator AND might not provide useful results as the two keywords may be located in very different parts of the document and might not be related to one another. It ensures that the document contains both terms and that they are located near each other. This operator is a more specific form of the AND operator. For example, searching for “Disney Land” OR “Disney World” will bring up results for either park. The OR operator is particularly useful when combined with quotations marks. You can see how this operator broadens your search, obtaining more results. If the left oval represents all documents containing the word “children” and right oval represents all documents containing the word “kids”, the green area represents documents that contain either word or both words. An example is children OR kids, which would return any document that had either of the words. This is very useful when searching for terms that have synonyms. If you want to broaden your search to find documents that contain either of the keywords, use the OR operator between words. You can see how this operator is useful in narrowing your results. If the left oval represents all documents containing the word “49ers” and the right oval represents all documents containing the word “schedule”, the intersection of those ovals, the green area, represents all documents containing both words. Here’s an example: Using the search criteria 49ers AND schedule would return all documents that contain both words. The engine will only find documents that have both words. If you want a document that contains all of your keywords, use the capitalized word AND between keywords. Here’s what these Boolean operators do for you: The Boolean operators AND, OR, NOT (or AND NOT in some engines), and NEAR allow you to create more specific search results. Perhaps the most useful feature in defining search criteria, Boolean operators provide you with powerful control over search engine logic. Find out a flight status by searching for the airline and flight number.If you want to figure out how many ounces are in a 3 pounds, type “ounces in 3 pounds.”.If you enter a mathematical equation, the search engine should give you the answer.Entering the tracking code for a package will bring up the shipping details.Quick searches work for many types of information, and don’t always require a keyword: If you need a definition, include the word “dictionary” before the word you want to define. For instance, if you want to find out the weather in Paris, simply type “weather Paris” and you should get the current forecast for Paris. Many search engines now allow you to quickly search for specific types of content, simply by including a keyword at the beginning of your search. The engine will return links to documents containing gardens, garden, gardener, gardeners, and so on. However, if your results are limited in number (though not likely with gardening) and you want to broaden your search, use a root part of the word and abbreviate it with an asterisk (garden*). If you are looking for information on gardening, you could use it as your keyword. Here’s an example: When searching for information on gun control legislation, using “gun control” eliminates documents that contain the words gun and control, but not in that order, and possibly having nothing to do with gun control. When using search terms containing more than one word, enclosing them in quotation marks, returns documents containing the exact phrase only.
