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