• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu hoach)) ky danh cay phoi. lieu va cau duc va hanh vi ((luu tre) OR (luy tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu hoach)) ky danh cay phoi. lieu va cau duc va hanh vi ((luu tre) OR (luy tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu hoach)) ky danh cay phoi. lieu va cau duc va hanh vi ((luu tre) OR (luy tre))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu hoach)) ky danh cay phoi. lieu va cau duc va hanh vi ((luu tre) OR (luy tre))*.
