Go3R - search technology from Germany that sorts results into facets. Information page must be striking a humourous pose with its opening paragraph -
"The project aims at developing a knowledge-based search engine for alternative methods to animal experiments in order to provide optimal search options for alternatives to animal experimentation. The first step consists of developing an ontology for the knowledge domain of alternative methods to animal experiments. Such an ontology represents a system of knowledge which permits logical deductions as a result of the numerous relationships between terms describing alternative methods it contains - in rough analogy to the possible connections between synapses in the brain."
Putting aside the 'animal experiments', you can experiment with pubmed searches at GoPubMed.
