Novoseek: a new Search engine for biomedical literature
Novoseek is a smart tool to find out easily and efficiently your literature from Medline database.
On the left side of your results list, you get clustering features suggesting filters (key biomedical concepts such as: Diseases, Genes, Organisms, Biological functions, etc.) linked to your request. That helps you to refine your search with one click.
My opinion: Excellent for Medline afficionados; Should replace the “old-fashion” PubMed!
