Ask HN: How to get near the top of search in GitHub?

I have a few projects that I'm working on that I'm getting close to wanting to have them publically available. They live in public repositories and if you enter the right search terms you can find them.

However, they show up at the bottom of the search. Projects with a couple of 40 line code files with almost no submissions rank higher than mine. In contrast, I have documentation (over 200 pages), libraries, unit tests, and so on.

Does it just come down to how many watchers you have, and/or forks? What kind of legitimate things can I do to get higher in the rankings?

A typical search yields between 10 and 250 hits - it's not like I'm fighting against 1000 narrowly different projects.

I've expanded my description to get more possible hit of keywords, and that works, but seems a bit manipulative. I want a short, readable description, not a large paragraph designed to get search hits.
