• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty nang) or (ty hang)) xa hoi. ((hieu tu) OR (hien tu)) cham xuc van hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) xa hoi. ((hieu tu) OR (hien tu)) cham xuc van hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ty hang)) xa hoi. ((hieu tu) OR (hien tu)) cham xuc van hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) or (ty hang)) xa hoi. ((hieu tu) OR (hien tu)) cham xuc van hanh vi cua tre*.
