Grrrrr help with map search

Every time I try to search c.l sites on the map search I get so frustrated can anyone put me right.

I put in a search for the area I want.... click on view site details......when I am done and want to return to the map where I left it with my chosen area to view another site ..... but when I use the back arrow it takes me back to the map but not with my chosen area search on so I have to start all over again.

Please please tell me what I need to do before I pull my hair out
