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