MISCELLANEOUS

      Our search engine is not case-sensitive. In other words, it makes no difference whether you search for World Wide Web or world wide web; both searches yield the same result.
      Some key words generate errors. For example, searching for every instance of the word the will result in an error being returned since virtually every article in the database contains this word. Certain other key words might yield similar results. For example, searching for the word page is too broad since this word appears in every article as part of the page number.
      The search engine ignores periods. For example, entering the word U.S.A. or USA will yield the same result.
      An ampersand (&) is interpreted by the search engine as the word and. If you need to search for a word or words with an ampersand, as in AT&T, substitute a plus sign for the ampersand; i.e., AT+T.
      Other lesser-used characters in key word searches can result in errors. For example, it's best to avoid question marks, brackets, percent signs, etc. These characters, in certain instances, convey specific instructions to the search engine that might cause unexpected results. For example, the question and exclamation marks are reserved by the search engine as wildcard characters that substitute for missing or unknown letters.
