• Performing a fuzzy search may retrieve terms with similar spellings: thuat song ty nang o hoi. hieu ((va tham) or (vu cham)) ((tuc va) OR (tuc xa)) hanh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat song ty nang o hoi. hieu ((va tham) OR (vu cham)) ((tuc va) OR (tuc xa)) hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat song ty nang o hoi. hieu ((va tham) or (vu cham)) ((tuc va) OR (tuc xa)) hanh va cua tre*".
