specific words that
will be in the pages you want. All of these
search engines accept quotes ( " " ) to form phrases. Use OR
(capitalized) to search for either of two or more words or "phrases."
Use AND (capitalized) search two or more words on a page but not
necesarilly next to each other as in the "phrase"
search.
