• Performing a fuzzy search may retrieve terms with similar spellings: bo sach ky nang ((x hoi) or (o hoi)). thi nang cham xuc va ((hanh vai) OR (hanh va)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach ky nang ((x hoi) OR (o hoi)). thi nang cham xuc va ((hanh vai) OR (hanh va)) cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach ky nang ((x hoi) or (o hoi)). thi nang cham xuc va ((hanh vai) OR (hanh va)) cau tren".
• Adding a wildcard symbol may retrieve word variants: bo sach ky nang ((x hoi) or (o hoi)). thi nang cham xuc va ((hanh vai) OR (hanh va)) cau tren*.
