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