• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tu nang x hoi. hieu ((ve cam) or (va cam)) ((luc van) OR (duc van)) hanh lam cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu nang x hoi. hieu ((ve cam) OR (va cam)) ((luc van) OR (duc van)) hanh lam cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu nang x hoi. hieu ((ve cam) or (va cam)) ((luc van) OR (duc van)) hanh lam cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach tu nang x hoi. hieu ((ve cam) or (va cam)) ((luc van) OR (duc van)) hanh lam cua tre*.
