• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky ((tang luan) or (trong van)) hoi. hieu ((ve cam) OR (ve cham)) xuc va dinh de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky ((tang luan) OR (trong van)) hoi. hieu ((ve cam) OR (ve cham)) xuc va dinh de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky ((tang luan) or (trong van)) hoi. hieu ((ve cam) OR (ve cham)) xuc va dinh de cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sac ky ((tang luan) or (trong van)) hoi. hieu ((ve cam) OR (ve cham)) xuc va dinh de cua tre*.
