What issue do you have?

Basic search works fine with most non-alphabetical characters such as ~, !, #, and =. However, when I tried to search plus sign, +, nothing came up. I can't think of what makes it so special among others. Is there another way to search plus sign?

Note that I didn't empty between quotes every time I typed the next character in the first screenshot. It's because an empty basic search (/"") acts like nothing is typed in the search bar, so all notes will be listed. Still, I was able to search most special characters by typing in between the quotes, however, the plus sign acted like nothing was typed in there and thus all notes will be listed. Please refer to the second screenshot for this matter.
