• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky mang luoi hoi. hieu doc chat ((xuc va) OR (((tuc va) OR (thuc va)))) hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky mang luoi hoi. hieu doc chat ((xuc va) or (((tuc va) OR (thuc va)))) hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky mang luoi hoi. hieu doc chat ((xuc va) or (((tuc va) OR (thuc va)))) hanh vai cua te*.
