• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach 2 dang tay hoi. hieu va ((cham loc) or (cham soc)) va ((hanh vai) OR (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach 2 dang tay hoi. hieu va ((cham loc) OR (cham soc)) va ((hanh vai) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach 2 dang tay hoi. hieu va ((cham loc) or (cham soc)) va ((hanh vai) OR (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: thuat sach 2 dang tay hoi. hieu va ((cham loc) or (cham soc)) va ((hanh vai) OR (hanh va)) cua tre*.
