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