Not too bad; much less busy than 1L that's for sure.
As to your question, there are often reasons to enter a residence which do not give a right to search it for example exigent circumstances. Note also that an arrest warrant is less inclusive than a search warrant. If the police have an arrest warrant they may enter the suspects home and make an arrest but they aren't supposed to search the home. Furthermore, they cannot enter somebody else's home, if that somebody objects, with an arrest warrant.
