• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang cao) OR (nang ra)) hoi. lieu va ((cao xuc) OR (cao suc)) va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang cao) or (nang ra)) hoi. lieu va ((cao xuc) OR (cao suc)) va hanh vi cua te".
