• Performing a fuzzy search may retrieve terms with similar spellings: phu sang ky lang van hoi. lieu va cham oc van ((thanh di) or (((thanh de) OR (hanh de)))) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: phu sang ky lang van hoi. lieu va cham oc van ((thanh di) OR (((thanh de) OR (hanh de)))) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "phu sang ky lang van hoi. lieu va cham oc van ((thanh di) or (((thanh de) OR (hanh de)))) va triet".
• Adding a wildcard symbol may retrieve word variants: phu sang ky lang van hoi. lieu va cham oc van ((thanh di) or (((thanh de) OR (hanh de)))) va triet*.
