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