Yes, you can search* and PID indoors quite adequately with a modern weapon-mounted light, one with good output and adequate spill, using good technique. If you do not know how to do that, use a handheld to avoid waving your blaster around and muzzling things... and people ...you shouldn't.
You don't even really need any special gear, though. Your house does have built-in room illumination, right?
Alternatively, you can use your Tactical Audible Target Identification Friend-or-Foe System, or T.A.T.I.F.F.S.
You know, the one where you say "Who's there?" with your mouth.
*Although, really, why are you searching? If you're that sure that someone's in the house, why not just fort up and call the po-po and let whoever's in the house know that you've done so?
