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