Mercurius is a unique web search tool that helps you to narrow search engine and metasearch searches by listing keywords and phrases extracted from the web sites returned by a search. You can then repeat the search using any listed keywords you think are relevant, enabling you to reduce the number of results and find what you want. For example, a search on William Shakespeare returns more than a million results, but by using Mercurius and selecting Ben Jonson and quote from its list of suggested keywords, the search narrows to just a few hundred results, the first of which give Jonson`s famous quote about Shakespeare being not of an age, but for all time. So Mercurius search assistant can a) guide you to keywords that would give you a better result when you repeat a search, b) reveal connections that you didn`t know existed, and c) jog your memory as to what exactly you`re searching for. It works with Microsoft Internet Explorer and most of the major search engines and metasearcher sites.
