• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach su) OR (sach tu)) dang xa hoi. hieu van chat xuc ((va dau) OR (ca dan)) va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach su) OR (sach tu)) dang xa hoi. hieu van chat xuc ((va dau) or (ca dan)) va cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach su) OR (sach tu)) dang xa hoi. hieu van chat xuc ((va dau) or (ca dan)) va cua tre*.
