• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang van hoi. hieu va cac luc va ((((hanh tai) OR (hang tai))) OR (han tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang van hoi. hieu va cac luc va ((((hanh tai) OR (hang tai))) or (han tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky tang van hoi. hieu va cac luc va ((((hanh tai) OR (hang tai))) or (han tai)) cua tre*.
