yes they do check you. Typically, as part of the arrest process, there is a search. However, depending upon the circumstances, the search may take place before the arrest, or you may be under arrest and the search can take place after.

It could be one. There are search warrants and arrest warrants. If you have a search warrant, the police are entitled to search your property.

Yes and no. If the Police have a search warrant or your consent, they may search you. If they have neither and you're not under arrest, then no. This would be a 4th amendment violation and any evidence obtained through the illegal search would be suppressed. They may only search you incident to arrest, which means after they've verbally informed you that you're under arrest.
There is no public database for Arrest Warrants, because that information is not automatically available to the public. You, or your attorney, can inquire directly with the Police to find if there is a warrant for your arrest.
