Web Server – Prevents Multiple GET HTTP Request Methods

I have many queries like this one in the Apache log of my server:

"GET /? S = The + Upside HTTP / 1.0" 200 8831 "-" "Office"
"GET /? S = Godzilla HTTP / 1.1" 200 11604 "-" "Office"
"GET /? S = Step + Brothers HTTP / 1.1" 200 7921 "-" "Office"
"GET /? S = Lackawanna + Blues HTTP / 1.1" 200 7720 "
"GET /? S = Aladdin HTTP / 1.0" 200 9470 "-" "Desktop"

How can I prevent this request?
