• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang x hoi. lieu ((((va chai) OR (va chi))) OR (va cham)) cuc va thanh ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty nang x hoi. lieu ((((va chai) OR (va chi))) or (va cham)) cuc va thanh ve cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang x hoi. lieu ((((va chai) OR (va chi))) or (va cham)) cuc va thanh ve cua tre*.
