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