Change of filter search method

Instead of always having to remove filter and add again, for example when searching for secret codes, should be possible to only search a new code

Start by locating the filter and search UI, then trace how filters are removed and added when searching for secret codes. Confirm the current interaction and identify the relevant tests or entry points before defining the change. Done means a user can search for a new code without removing and re-adding the filter.
