Enhanced Visible Web Searching
Try more than one general purpose search engine for different results & rankings
Try a meta-search engine
More info at http://www.lib.berkeley.edu/TeachingLib/Guides/Internet/ MetaSearch.html
Use advanced search and/or results filtering for greater control over search input & results
