• Hyphenated author names: The npm registry API doesn't currently process hyphenated author names, so if you're searching for an author with a hyphenated name you'll need to use maintainer: instead.
• Scoped packages: The npm registry cannot currently provide download data for scoped packages. Consequently I'm filtering scoped packages from search results.
