Impossible search sometimes

Operating system

Windows

Joplin version

3.3.3

Desktop version info

All versions (desktop and portable)

What issue do you have?

In order to find quickly something in my notes I use combination of some keyboard caracters.
For example I use a lot "|-" (with no quotes)
In the past (many versions ago) it was possible to search that. Now it's not possible... (no search result)...
Thanks for help.
