Our most requested feature is to filter results by dependency name and version. For example: search for carousel repositories that depends on polymer > 1.0.0.

In order to do that, we first had to fetch dependencies from bower and npm. Fortunately, we've just pushed that and now a result looks like this:

{
  "id": 12217367,
  "name": "twitter-button",
  "description": "Web Component wrapper for Twitter's button using Polymer",
  "owner": {
    "id": 12434272,
    "login": "social-elements"
  },
  "created_at": "2013-08-19T13:29:28Z",
  "pushed_at": "2015-06-05T22:18:43Z",
  "forks_count": 16,
  "stargazers_count": 34,
  "default_branch": "master",
  "bower": {
    "name": "twitter-button",
    "keywords": [
      "polymer",
      "web-components"
    ],
    "dependencies": {
      "polymer": "Polymer/polymer#^1.0.0"
    }
  }
}

It's time to take the next step and develop this API. My idea is to have something like this:

/search/repos?q=carousel&dependency=polymer:^1.0.0

1. We would need to get the dependency value from request and split this string based on : operator.
2. Using the first part (polymer) we would have to filter the dependencies property
3. And with the second part (^1.0.0) we would have identify which versions satisfies or not (semver-regex could help us on that).

I'm not quite sure how to accomplish those steps... maybe Regexp Query? I don't know, any ideas?

The above link should include paper-date-picker as a top result, since it's an exact match. Also, items with the most stars are not appearing at the top.
