• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach v nang x hoi. hieu ((ve cam) OR (ve cac)) ((tuc va) OR (tuc xa)) hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach v nang x hoi. hieu ((ve cam) OR (ve cac)) ((tuc va) or (tuc xa)) hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu bach v nang x hoi. hieu ((ve cam) OR (ve cac)) ((tuc va) or (tuc xa)) hanh vi cua tre*.
