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