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