Can someone clarify this?

This is under Section 901.151 - Florida Stop and Frisk Law

"(5) Whenever any law enforcement officer authorized to detain temporarily any person under the provisions of subsection (2) has probable cause to believe that any person whom the officer has temporarily detained, or is about to detain temporarily, is armed with a dangerous weapon and therefore offers a threat to the safety of the officer or any other person, the officer may search such person so temporarily detained ***only to the extent necessary to disclose, and for the purpose of disclosing, the presence of such weapon***. If such a search discloses such a weapon or any evidence of a criminal offense it may be seized."

Does this mean that police can only search for an obvious weapon?

In other words, if you had weed in your wallet police can't open the wallet to search, right? Or even technically your pockets because they couldn't feel a weapon and they are trying to disclose the presence of a weapon, not a drug.(although I could see some police officers saying 'I "think" this is a weapon, let me take it out').
