• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((thu lang) OR (phu lang)) mai hoi. hieu ((ve pham) or (vi pham)) huu va thanh van cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((thu lang) OR (phu lang)) mai hoi. hieu ((ve pham) OR (vi pham)) huu va thanh van cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((thu lang) OR (phu lang)) mai hoi. hieu ((ve pham) or (vi pham)) huu va thanh van cua te".
• Adding a wildcard symbol may retrieve word variants: so sach ((thu lang) OR (phu lang)) mai hoi. hieu ((ve pham) or (vi pham)) huu va thanh van cua te*.
