The current search functionality allows to search for all tasks, last week or last month. This doesn't help with the following use case: "I have a week full of work planned but I want to make sure I included the task about X".

Current behavior: Many tasks show on the search sidebar, hard to find what I'm looking for, it generates frustration.

Expected behavior: It filters the Kanban view, only showing cards that match the search. Example case: I would see that card about "X" that I did had planned for Wednesday and avoid creating it again.
