• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach kem) OR (sach y)) nang xa hoi. thien van cham ((tuc va) OR (tuc xa)) kinh dat cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach kem) or (sach y)) nang xa hoi. thien van cham ((tuc va) OR (tuc xa)) kinh dat cua tre".
• Adding a wildcard symbol may retrieve word variants: toc ((sach kem) or (sach y)) nang xa hoi. thien van cham ((tuc va) OR (tuc xa)) kinh dat cua tre*.
