• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. thien ((van lam) OR (van nam)) duc ban thanh ((moi cua) OR (doi cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. thien ((van lam) or (van nam)) duc ban thanh ((moi cua) OR (doi cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. thien ((van lam) or (van nam)) duc ban thanh ((moi cua) OR (doi cua)) tre*.
