filter applies a Filter fil to the databank. This will only show questions who match the full keyword in the filtered category. Multiple filters can be applied, and are removed using unfilter. filter differs from search due to filter only being able to filter by a full categorical symbol, while search can use partial words on any category.

Parameters:

fil - - filter to search databank with
