• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang o hoi. hieu ((ve cam) or (ve chat)) xuc van thanh lap ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang o hoi. hieu ((ve cam) OR (ve chat)) xuc van thanh lap ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang o hoi. hieu ((ve cam) or (ve chat)) xuc van thanh lap ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang o hoi. hieu ((ve cam) or (ve chat)) xuc van thanh lap ((cua tre) OR (cua te))*.
