• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang tao) OR (huang tao)) annex 2 ((gender 2.3) OR (gender 1.3)) beam modes saul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang tao) or (huang tao)) annex 2 ((gender 2.3) OR (gender 1.3)) beam modes saul ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang tao) or (huang tao)) annex 2 ((gender 2.3) OR (gender 1.3)) beam modes saul ;*.
