Perhaps you should try some spelling variations:
variable duplication » variable application (Expand search), partial duplication (Expand search), variable realization (Expand search)
duplication problem » lubrication problems (Expand search), equalization problem (Expand search), location problem (Expand search)
function variable » functional variables (Expand search), function variants (Expand search), function variant (Expand search)
