• If you are trying to use Boolean operators, they must be ALL CAPS: %((_quality control) OR (byquality control))%((2c reliability) OR (((((ic reliability) OR (8 reliability))) OR (9 reliability))))%4 safety AND risk%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((_quality control) OR (byquality control))%((2c reliability) or (((((ic reliability) or (8 reliability))) or (9 reliability))))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) OR (byquality control))%((2c reliability) or (((((ic reliability) or (8 reliability))) or (9 reliability))))%4 safety and risk%22*.
