In order to identify scientific publications you must select the "Science" database (next to the search bar) before launching your query.
The results are ranked not around the documents but around the most relevant experts. Indeed, ranking the results around the most cited documents (as in the case of Google Scholar, for example) has the disadvantage of favoring possibly older documents that have had 'time' to be cited. Ranking around the most relevant authors, on the other hand, makes it possible to find the most recent papers written by the most relevant authors, even if they are not yet widely cited. The other advantage of proceeding in this way is that you can immediately identify the authors with whom you could start a conversation or establish a partnership: you do not waste time contacting the author of a highly cited paper who has only occasionally worked on a subject.
