• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach tai vu anh khong he thong ) OR ( tu cac ((tro truc) OR (tho tru)) cach hoa hoa thong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach tai vu anh khong he thong ) or ( tu cac ((tro truc) OR (tho tru)) cach hoa hoa thong ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach tai vu anh khong he thong ) or ( tu cac ((tro truc) OR (tho tru)) cach hoa hoa thong ))*.
