• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach tham)) nang xa hoi. thien van cham duc toan anh ((lam va) OR (dam va)) trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tham)) nang xa hoi. thien van cham duc toan anh ((lam va) OR (dam va)) trien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach tham)) nang xa hoi. thien van cham duc toan anh ((lam va) OR (dam va)) trien".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach tham)) nang xa hoi. thien van cham duc toan anh ((lam va) OR (dam va)) trien*.
