• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sach y)) nang x hoi. thien van ((bac nuoc) OR (cac nuoc)) va nang tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sach y)) nang x hoi. thien van ((bac nuoc) or (cac nuoc)) va nang tai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) OR (sach y)) nang x hoi. thien van ((bac nuoc) or (cac nuoc)) va nang tai cua tre*.
