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