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