Hint: you can indicate negative keywords with hyphen prefix, e.g.{' '}
<code>-react -ng- chart</code> as searching for <code>chart</code>{' '}

Hint: multiple keywords are combined with "and" for most fields, but
they're combined with "or" for programming languages.

Hint: the keyboards are matched partially for most fields, but is
matched exactly for programming languages. So searching{' '}
<code>Java</code> will not match <code>Javascript</code> repos.

Hint: if a keyword is wrapped with double quotes, it is matched in full.
For example searching <code>speed</code> will matched for{' '}
<code>frank-dspeed</code> but searching <code>"speed"</code> will not
match for that user. This feature does not apply to the language field
as it's always matched in full.
