Hello,
Unlike regular Scholar search, the new "Labs" ranks papers on text matching alone, rather than number of citations and journal recognition. (Feels a bit like google search 20 years ago, when you could find anything on the web if you knew the specific wording.)
Each search result has a 2-bullet AI summary why it relates to the query, so minimal fluff text to go through.
