• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thien hach) OR (thien thanh))) OR (chieu sang)) - thanh trung cap nhung cong dan khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thien hach) OR (thien thanh))) or (chieu sang)) - thanh trung cap nhung cong dan khan cap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thien hach) OR (thien thanh))) or (chieu sang)) - thanh trung cap nhung cong dan khan cap*.
