Filter „heading“ doesnt work

[SirBooks]

If i try to set the filter „heading“ like:

heading does not include Mark

i still get tasks with the corresponding word - why?

The option with „heading includes X“ also doesnt work

That option definitely does work, has thorough unit tests, and there has been no other such bug reports from many thousands of users.

So my money is on there being a problem or with your tasks or your query.

If you want to show me the full markdown text of one of your tasks that you believe matches that query, I will have a look.

Query:
`tasks
not done
due today
heading does not include Mark

Task:

• this is a test to Mark📅 2023-05-04

or as attached file:

today.md

thanks for helping!

Thanks for the example file - it really helped.

D'oh. It took me a minute to realise the problem...

heading searchings the heading, as in ### I am a level 3 heading that the task is in.

description is what you want. It searches the task's description, which is what contains the Mark here.
