• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly ((nang o) or (nang ho)) hoi. hieu ((va cham) OR (va chat)) duoc va thanh dan cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((nang o) OR (nang ho)) hoi. hieu ((va cham) OR (va chat)) duoc va thanh dan cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((nang o) or (nang ho)) hoi. hieu ((va cham) OR (va chat)) duoc va thanh dan cua cu".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((nang o) or (nang ho)) hoi. hieu ((va cham) OR (va chat)) duoc va thanh dan cua cu*.
