• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc dieu) OR (hoc thieu)) xanh - hanh ((trang cua) OR (trung cua)) cong nong tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc dieu) or (hoc thieu)) xanh - hanh ((trang cua) OR (trung cua)) cong nong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc dieu) or (hoc thieu)) xanh - hanh ((trang cua) OR (trung cua)) cong nong tan toan ban*.
