• Performing a fuzzy search may retrieve terms with similar spellings: vu sai ky trong van hoc. ((hieu van) OR (hieu va)) cam ((xuc va) or (luc va)) dao de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky trong van hoc. ((hieu van) OR (hieu va)) cam ((xuc va) OR (luc va)) dao de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky trong van hoc. ((hieu van) OR (hieu va)) cam ((xuc va) or (luc va)) dao de cua triet*".
