 ### Search by topic or language only
 `gh-s` allows to skip prompting for a repository name by passing the `-E` flag; this in turn implies that the query searches against all possible GitHub repositories, which may result in longer response times. Notice furthermore that `-E` must always be accompanied by at least another non-empty flag. Use with care, however it does allow for some interesting statistics or general curiosity: check the [Wiki](https://github.com/gennaro-tedesco/gh-s/wiki/Common-queries)!
