Search GitHub issues by title, only

tl;dr You can search GitHub issues specifically only in the title by adding in:title.

Suppose you go to a GitHub repository's Issue list. If you search, it will find issues that match your search in any field. For example:

Finding 70 issues by dialog

Now, add in:title to the search input:

Finding 30 issues by dialog when only searching in the title

I use this all the time when I know that the search input has to be in the title. Especially when you know what you're looking for.

Perhaps I should implement this on my own blog?

UPDATE

My friend @andyfeller reminded me that this page has all the "tricks" listed:
