• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) dang xa hoi. lieu va cac tuc va dan vai ((cu tren) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) dang xa hoi. lieu va cac tuc va dan vai ((cu tren) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) dang xa hoi. lieu va cac tuc va dan vai ((cu tren) or (cua te))*.
