[Function request] Excluding the designated categories themselves from the result

[DP-jawiki]

When searching so-called container categories, the designated categories for search can be noisy in themselves at the result.
Could you implement an additional function button to exclude the designated categories themselves from the result list?

Best Wishes.

Can you not add it to the "Negative categories" with depth 0 ("|0")?
