• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang van hoi. hieu ve cac luc va ((thanh ca) or (((thanh cac) OR (tranh cac)))) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang van hoi. hieu ve cac luc va ((thanh ca) OR (((thanh cac) OR (tranh cac)))) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang van hoi. hieu ve cac luc va ((thanh ca) or (((thanh cac) OR (tranh cac)))) cua tre*".
