• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((thu lang) or (phu lang)) ha hoi. hien thi ((cham so) OR (ham so)) ban hanh via va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((thu lang) OR (phu lang)) ha hoi. hien thi ((cham so) OR (ham so)) ban hanh via va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((thu lang) or (phu lang)) ha hoi. hien thi ((cham so) OR (ham so)) ban hanh via va triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ((thu lang) or (phu lang)) ha hoi. hien thi ((cham so) OR (ham so)) ban hanh via va triet*.
