Google is still recognized as the best general web search engine. Recognizing this, we have decided to offer a "Googling to the Max" course in which we teach how to use Google really well, taking advantage of its features and negotiating around its weaknesses.Google is the BIGGEST search engine database in the world. Google has many useful ways to limit searches. Google offers special "fuzzy"(模糊的) searches that are useful to search synonyms (同义词), find definitions, find similar/related pages, and more. The shortcuts and special Google databases can enhance certain types of research.Let’s sec if Google has a dictionary feature. There are two different ways to find a word’s definition using Google. First, you can type the word in the Google search box. If it has a dictionary definition, the word will appear in the right hand side of the blue bar that stretches across the top of your search results. For one-word terms, "[definition]" appears next to the word. Clicking on that link will display the word’s dictionary definition. If a query contains more than one word, each word will appear underlined. Simply click on a word to view its dictionary definition. You also can search for a word’s definition by typing [define:] into the Google search box followed by the word or phrase you’re looking up. If we’ve seen definitions for that word or phrase on the web, we’ll retrieve (找到，寻回) and display them. How many ways are there to get a word's definition when you study（）
