Google allows users to search simply by typing keywords or use more advanced techniques. Basic searches involve entering one or more keywords and Google will return relevant web pages. Users can focus their searches by adding more precise keywords. Google matches search terms to pages on the web, so it's best to use the actual terms likely to appear on pages rather than synonyms. Keeping searches concise with descriptive keywords yields better results than overly specific or common words. Google also looks for other forms and variations of search terms through stemming.
