developing land » developing inland, developing brand, developing plans
land africa » can africa, fund africa, plan africa
time wages » time wage, time images, time water
1.4 4 » 1.4 _, 1.4 a, 1.4 r
1.4 b » 1.4 _, 1.4 a, 1.1 b

• The words AND, OR and NOT may confuse the search; try adding quotes: "technology _ innovation space time wages compensation ((1.4 4) OR (1.4 b)) developing land africa.~".
• Adding a wildcard symbol may retrieve word variants: technology _ innovation space time wages compensation ((1.4 4) OR (1.4 b)) developing land africa.*.
