Scenario Search items?

[Pod]

A few of the scenario and hero cards make reference to "Scenario Search" items. Unfortunately I couldn't find a single mention in the rulebook. Is a Scenario Search item special in any way or is it just a reminder to look out for them + a classification that some of the hero cards work on?

I ask because I bought & played the vanilla game with some friend the other day and we agreed that Scenario Search items act like "Pick Up:" areas. That is, if you're in a building you can either search or take a scenario search item from the discard deck. Looking back now, this seems a bit stupid.
