/* By default, this search operates under the */
/* assumption that the user wants the results to */
/* contain all search words. If the user wishes */
/* to negate this functionality, he can do this by */
/* using the OR operator. Using the OR operator, */
/* the user can specify certain sets of words, of */
/* which, only one set has to have all of its */
/* search words found. */
/* */
/* For example, a search for: */
/* */
/* seo OR search engine optimization */
/* */
/* will return results that contain seo, search */
/* engine optimization, or both. */
/* */
/* If the user wants to match an exact phrase, he */
/* can do so by putting the search string in quotes.*/
/* */
/* For example, a search for: */
/* "Website Software" seach engine optimization */
/* */
/* Will only return results that contain the */
/* exact phrase "Website Software" and the words */
/* search, engine and optimization. */
/* */
/* If a user would like to pick only results that */
/* don't contain a certain keyword, a user may do so*/
/* by using the subtraction operator. */
/* */
/* For example: a search for: */
/* "Website software" -sitemapper */
/* */
/* Will only return pages that contain the phrase */
/* "Website software" that also do not contain the */
/* word sitemapper. */
