Karen Blakeman gibt im Blogpost «Essential Non-Google Search Tools for Researchers – Top Tips» einige nützliche Hinweise auf Suchmaschinen jenseits von Google. Nicht gekannt habe ich z.B. die Blog- und Twittersuche «Meltwater IceRocket» (Tipp 9):
«IceRocket specialises in real-time search and was recommended for inclusion in the Top Tips for its blog search and advanced search options. There is also a Trends tool that shows you the frequency with which terms are mentioned in blogs over time and which enables you to compare several terms on the same graph. Very useful for comparing, for example, mentions of products, companies, people in blogs.»
