• If you are trying to use Boolean operators, they must be ALL CAPS: %((_quality control) OR (byquality control))%((((2c reliability) OR (24 reliability))) OR (((11 reliability) OR (((5 reliability) OR (2 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 (24 reliability))) or (((11 reliability) or (((5 reliability) or (2 reliability))))))%4 safety and risk%22".
• Adding a wildcard symbol may retrieve word variants: %((_quality control) or (byquality control))%((((2c reliability) OR (24 reliability))) or (((11 reliability) or (((5 reliability) or (2 reliability))))))%4 safety and risk%22*.
