Hi @Maggie8K , @pietkuip , @TomorrowTamara:
I did post a reply in a different topic on animal filters. (That feeling when it takes you 15 minutes to find your own post…)
The long-story-short is that the animal filters treat some animals (cats/dogs) differently than others (horses/poultry/etc.). So, I wouldn’t be surprised if other filters act similarly unintuitively. You’d just have to test them.
And to address OP’s questions a bit more: I’m sure it’s possible to change the search logic in the code. But you first have to convince TH that they should do that. =) I’m not sure who makes that decision. Maybe someone on the “Product” team.
When filters were added this year, there was a default chosen, but I forget what it was. So yes, a lot of sits may still have the default, whether correct or not.
