• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sai) or (vu dai)) ky tang van hoa. hieu van cam xuc va kinh de ((cua tre) OR (cua te))~.
• 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 xuc va kinh de ((cua tre) OR (cua te)).
• 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 xuc va kinh de ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((vu sai) or (vu dai)) ky tang van hoa. hieu van cam xuc va kinh de ((cua tre) OR (cua te))*.
