Lookup
Lookup is the built-in way of both searching for and creating new notes. You can find it in the command palette or you can assign a hotkey to it for quicker access.
It's recommended to always use Lookup to create new notes
The Lookup modal searches both through the file name and any title properties (See: Special Properties). That means you don't have to remember the whole path to get a match.
If, for example, I'm looking for my note on "Time Blocking", I can start by searching for "Time Block" and it will show up:
If a path or title cannot be found, you can use the "Create New" option to instantly create a file with the path you've typed in.
