• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (thuat san)) thi hang van hoc. hieu ve cam ((xuc va) OR (duc va)) tinh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat san)) thi hang van hoc. hieu ve cam ((xuc va) OR (duc va)) tinh ha cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (thuat san)) thi hang van hoc. hieu ve cam ((xuc va) OR (duc va)) tinh ha cua viet*".
