When the person and/or place is considered a national threat under the Anti-Terrorism Act. In other words if they say they thought you might be a terrorist or affilated in some manner to such people or places fequented by known terrorists or even suspected terrorists. Or if there is propapable cause I.E. pills spilled, smells like marijuana, blood is seen, ect. So basically you need to ask if you are under arrest the second that you are requested to ok a search of person, property, or home. If you are not under arrest you can request that the officer provide you with a search warrent-if you yourself dont sign it, it has to be signed by a judge. Depending on what time of day it is that can take anywhere from 15 minutes to 8 hours.
Under "normal" circumstances the police require a warrant. However, there are exceptions (as there are in ALL things) Several instances when which a search warrant is not needed: one might be when the police are in "fresh pursuit" - another would be "under exigent circumstances" - another would be if the occupant in charge of the premises gives their permission. Etc. - etc.
There are several situations in which a search warrant is not required in order for the police to search and seize evidence. The exceptions to the warrant requirement are: (1)stop and frisk situation--also known as a terry stop (2)when the police have the consent of the individual or someone who also lives in the house (3)when the search involves an automobile (4)when the illegal item is in plain view and the police are on the property pursuant to a proper search warrant (5)when the search is incident to an arrest (6)and when there is an emergency type situation such as in hot pursuit of a suspect or there is the fear that the individual may destroy evidence before a search warrant can be obtained.

They must provide a judge with probable cause to do a search.
A warrant may be necessary for the police to search the server that Facebook is running on. It is also possible that FB may choose to allow the search without a warrant. If the 'search' is simply examining publicly available information on any web page, no. A warrant would not be necessary.
Ive heard of police with a search warrant finding something non-related to the search warrant, and then issuing a new search warrant on the spot regarding the new issue.
Yes. The occupant/resident need not be present at the time the warrant is executed.
yes they have to have a paper signed by a judge
Yea
no they do not have to show you all they need is the search warrant. But what you should have done is to see the warrant. Sorry
Yes. The police can search any items if they have a warrant. It does not matter that no one is there to receive the warrant. The police only have to leave a copy of the warrant at the residence.
