• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ((ly vang) or (ly hang)) x hoi. hieu ve cau truc ((va hanh) OR (va thanh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ((ly vang) OR (ly hang)) x hoi. hieu ve cau truc ((va hanh) OR (va thanh)) di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ((ly vang) or (ly hang)) x hoi. hieu ve cau truc ((va hanh) OR (va thanh)) di cua triet*".
