STOP words

Stop words are common words that databases or search engines simply ignore while running a search. These words have little intrinsic meaning and usually modify other words - such as adverbs, prepositions and conjunctions. Some examples of stop words are: almost, with, approximately, it, be, then, these.

Some databases provide ways to force the system to search for the word or the word in a particular phrase. Check the HELP to identify the appropriate syntax in your favorite database or search engine.
