Generally these formulas are based on how many times your search terms appear on the page or how near the top of the page they occur. Sometimes this results in very strange results, so it s best to use as many words relevant to your search as possible. These search engines are best used when searching for very specific information. For example, if you were searching for information about human rights violations in the town of Huehuetenango, Guatemala, one of these search engines might be very useful. Whereas if you want general information about human rights in Guatemala, these search engines would probably be less useful.
Most search engines use Boolean operators to help make a search more specific.
Some search engines use similar operators to help you narrow down a search. Quotes are used for phrases and are useful when searching for people s names. Note that some names may be alphabetized by last name. You may also want to try using Lukashenko by itself as his name may not always appear as Alexander Lukashenko. Remember to be careful with upper and lower case.
