• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang xa hoi. hieu ((ve cam) OR (ve cham)) ((xuc van) or (duc manh)) hanh vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xa hoi. hieu ((ve cam) OR (ve cham)) ((xuc van) OR (duc manh)) hanh vai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang xa hoi. hieu ((ve cam) OR (ve cham)) ((xuc van) or (duc manh)) hanh vai cau tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang xa hoi. hieu ((ve cam) OR (ve cham)) ((xuc van) or (duc manh)) hanh vai cau tren*.
