A search engine is computer software used to locate a user specified word, phrase, image, sound or other page or file located on the World Wide Web. Each search engine builds and rebuilds its database through scripts followed by automated web crawling scripts. When using sites or other resources located through a search engine, be sure to record the url and the date you accessed that resource; you may not be able to replicate the exact same search to reach it again.
Boolean operators are delimiters or search command structuring symbols (composed of letters and punctuation marks). Each search engine utilizes Boolean operators but they do not all use exactly the same operator to indicate identical commands. Be sure to review the use of Boolean operators employed by a search engine before using them to enhance your search precision.
