• If you are trying to use Boolean operators, they must be ALL CAPS: %((((biomass transfer) OR (mass transfer))) OR (((((mass transports) OR (mass transport))) OR (airways transport))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((biomass transfer) OR (mass transfer))) or (((((mass transports) or (mass transport))) or (airways transport))))%22".
• Adding a wildcard symbol may retrieve word variants: %((((biomass transfer) OR (mass transfer))) or (((((mass transports) or (mass transport))) or (airways transport))))%22*.
