• Performing a fuzzy search may retrieve terms with similar spellings: tu lang ky va cap phoi. hieu ((ve cam) OR (ve cham)) tu va danh vi ((dua tren) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu lang ky va cap phoi. hieu ((ve cam) OR (ve cham)) tu va danh vi ((dua tren) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu lang ky va cap phoi. hieu ((ve cam) OR (ve cham)) tu va danh vi ((dua tren) or (cua te))*".
