• Performing a fuzzy search may retrieve terms with similar spellings: vu sai ky dang van hoc. hieu phan dau ((luc va) OR (duc va)) ((thanh cha) or (thanh chac)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky dang van hoc. hieu phan dau ((luc va) OR (duc va)) ((thanh cha) OR (thanh chac)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky dang van hoc. hieu phan dau ((luc va) OR (duc va)) ((thanh cha) or (thanh chac)) cua tre*".
