Scholar Ninja: a distributed search engine for science
This is based on an experimental Chrome extension (available at https://chrome.google.com/webstore/detail/scholar-ninja/mngpckgljabecionknlpnnbamopcehgp?utm_source=blog) which will search across scholarly sites. It doesn’t aim to lead to full text, merely to provide an easily searchable index for scholarly content.
Scholar Ninja is a new tool and still under development but it may develop into an interesting site. Read more about it at http://juretriglav.si/an-open-distributed-search-engine-for-science/
