This past year Hakia went through a refresh changing its interface but more importantly the search capabilities and the way the results are presented. I really like the fact that you are searching in a true semantic fashion through Qdexing (coined by Hakia).
General semantic search engines have a really hard task: making sense of very broad and very large sets of data. Many of the general semantic engines are subject for research papers and conference talks; few general semantic engines are of practical use to sourcers for now.
Internet search enthusiasts are craving new opportunities to delve deeper into the world of search. I recently spoke with Gary Clarke of Wolfram Alpha to learn about the new Alpha search engine that claims to have changed search forever. Take a read on True Semantic/Natural Language search.
