I have several tasks in an org file, some of which which have an Effort property and some of which which don't.
** Example Task 1, with effort :PROPERTIES: :Effort: 1:30 :END: ** Example Task 2, without effort :PROPERTIES: :END: When I run a match query in the agenda (C-c a m) and want to check by effort, this tutorial suggests the following. Suppose I want to match all todo tasks whose efforts are estimated to be less than 2 hours. I would do:
Match: +Effort<2/TODO However, this also displays todo items which do not have an Effort property. (Example Task 2 would be shown along with Example Task 1.)
How can I make it so that having no Effort property results in not appearing in an Effort query?
