Every significant search engine is equipped with tools calledBoolean operators. Taking the time to learn how to use them candrastically improve your search results for some types of searches.Unfortunately most of us are completely unaware they even exist.An Example of the power of the Boolean tools is the use of the word"and" in narrowing down your search area. It could actually mean thedifference in receiving 10,000 returned results and only 100.The Boolean tools are so powerful at doing what they do, a number ofsearch engines are automatically incorporating them into theirsearches. In other words, if your using one of these search e-sources to search for "maps,Africa" what your actually searching foris "maps and Africa". This can be a good thing. Without the "and" inyour search in the above example your results would includethousands of unwanted "map" sites. With the inclusion of the "and"your results will only contain map sites with Africa included.At the same time if your unaware of the Boolean tools use of the"and" in your search it can just as easily filter out results thatare 100% pertinent to your query.An example of this would be a search string like " maps, Africa,poverty," This could be a very legitimate search if you were doing apaper on the areas of poverty in Africa. Unfortunately if the searche-source your using is also automatically using Boolean tools yoursearch results will all have to contain the words "maps and Africaand poverty" thus narrowing your results down far beyond anythingyou really wanted. (see list of automatic Bolean search e-sources atthe end of this article)What does all this really mean for you and your searches? Wellactually it means quite a bit. If your unaware of how the search e-source is looking for your information you'll probably not end upwith all of the most pertinent information available.If you are aware of the power of the Boolean tools your searcheswill now be a much less painful experience. You'll spend far lesstime searching, and you'll return far more relevant results."Automatic Boolean search engines are AltaVista, AOL Search, Google,HotBot, Lycos, MSN Search, and Northern Light.""Your Success Is Our Success" jbp Article Tags: Boolean Tools
