I've added a very basic search function to the site. You can search over package names. This is great if you have a rough idea of what you're looking for.
It's also OpenSearch compliant, so if you're using a suitable browser (e.g. Chrome), it'll let you search directly from the address bar. This is super convenient. If I'm looking for documentation for
mixtools, I type R-P-A, Chrome autocompletes the rest, TAB puts us in the search box, and then I can type 'mixtools'. Easy peezy.
