• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. lieu va ((dau nuoc) OR (dat nuoc)) va dan ((thai cho) OR (thai cao)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. lieu va ((dau nuoc) or (dat nuoc)) va dan ((thai cho) OR (thai cao)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. lieu va ((dau nuoc) or (dat nuoc)) va dan ((thai cho) OR (thai cao)) tre*.
