• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((ty hang) or (ky nang)) ma hoa. hieu ((ve cam) OR (ve cac)) xuc van thanh ha cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty hang) OR (ky nang)) ma hoa. hieu ((ve cam) OR (ve cac)) xuc van thanh ha cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty hang) or (ky nang)) ma hoa. hieu ((ve cam) OR (ve cac)) xuc van thanh ha cua triet*".
