I was surprised that somwhere along the line within the past few updates, that choosing multiple filtering options when refining item searches became possible... and just as quickly, it vanished.
It was possible to select something like 'used' and 'parts and repair' for item condition (with check marks next to each choice showing, as they were selected), and apply them together.
Sadly, it's reverted back to only allowing a single choice per filter.
