• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly nang x hoi. hieu va cham duc va ((danh vi) OR (hanh vi)) ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang x hoi. hieu va cham duc va ((danh vi) OR (hanh vi)) ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang x hoi. hieu va cham duc va ((danh vi) OR (hanh vi)) ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang x hoi. hieu va cham duc va ((danh vi) OR (hanh vi)) ((cua tre) or (cua te))*.
