Slightly off topic, but I find the current academic lens misleading, to me it appears as "search for papers and other academic resources", not "search .edu domains + some universities".
The search "high performance sparse polynomials" with the academic lens, while it returns the paper I wanted, it does not return the original source, https://ir.lib.uwo.ca/etd/5593/ . A normal kagi search returns this as the top result.
