How to use the filter function to find the story for you?

Usually what I would do first is to select a specific relationship in a fandom, and then I select the rating, characters, and some additional tags, such as hurt/comfort, humor, romance, and friendship, etc.Lastly, I select "date updated" or "kudos" under "sort by", and I click "complete only" under status.
