I'm not sure. It looks like algolia add more weight to the title than the url??? Or perhaps it's because in "[InfoQ]" it is a complete word, but in "infoq.com" it's a partial word???
Agree, some search magic going on. Though I would expect a different ranking when I sort by "Popularity". And searching for "infoq.com" [1] gives even worse results imo. But ok, results expectations can be highly subjective :)
