Exclude properties for filters in the search, but do not exclude them globally in all categories.
So far, it is only possible to set a property as filterable and non-filterable. The problem here is that a property that is not filterable can no longer be individually selected as a filter in the categories. However, if you do not want to have all possible properties as filters in a normal shop search, you have no other option than to deactivate the filtering of the property for the entire shop and can then no longer use the property as a filter in categories.
For the categories, you can set individually which properties should be displayed as filters. Such a setting option for the search would also be very helpful for customers or at least the option to exclude the property only for the filters in a search.
