• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sac ky) or (cac ky)) tang ma hoi. hieu ve cam xuc va ((hanh du) OR (hanh dua)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sac ky) OR (cac ky)) tang ma hoi. hieu ve cam xuc va ((hanh du) OR (hanh dua)) va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sac ky) or (cac ky)) tang ma hoi. hieu ve cam xuc va ((hanh du) OR (hanh dua)) va triet*".
