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