Binx's search is strange. He continually mentions it, without ever actually deciding what he is looking for. This is why I think that his search is actually a search for something which he can then search for. It sounds confusing, but is simple really. Binx is a man who has done various things over his life. He was in a fraternity in college, joined the military after it, and now runs around chasing his secretaries. He doesn't seem to know anything about what he wants out of life. Work is about all he knows, and he still uses this as a tool for going after women.

He creates an illusion of a "search", probably to be able to tell himself that he is doing something with his life. A likely cause of this is his experiences in the Korean War. They have left him a stranger to his own life. The war shattered things he had previously believed, and he doesn't know what he wants anymore. Before, it had been about having a good time, then eventually going to work. His wartime experiences have created a new set of beliefs inside him, that he is still unsure of.Binx wants to find a meaning in his life, to find his identity. He just doesn't know how. I believe he is trying to find these things through the search, but he does not yet know what to search for.
