Using keywords to refine an Internet search

You may not know much about the topic you're searching; that's why you're searching it, right? Start with a couple of high level words and then look through the results for words that describe more closely what you want. For example, suppose you would like to install a Pergo-like floor in your house, you might start by entering "Pergo floor" in your search engine. The results will show you that Pergo is one brand among many laminate floors. A refined search on "laminate floor" and "how to install" will provide you with the needed information. Other searches on "laminate floor" and "price" and "cost" will tell you how much you can expect to pay. Putting two words for essentially the same thing (i.e. price and cost) in your search will increase your chances of results that provide the information you're looking for.
