Studied and worked in law. Im not making it up
The way it is in The Netherlands...and I think more EU countries.
Police cannot search random people on the street. They need a suspicion, a reason to search you. That reason cannot be the simple fact you seem to be going out to a club because you are in that area or in a taxi near the club. Sometimes they will stop your car and ask if you will let them search your car voluntary, but that's your choice then. There's one exception, when a mayor declares a certain area to be at risk for crime and then they can search you randomly. But that's only in a limited timeframe and area.
Now bouncers is another thing. You enter a venue, so you comply with the rules that venue has. If one of those rules is: no drugs and weapons and you can be searched for that. You comply with the search by entering the venue.
