• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang x hoi. hieu va pham ((chuc ban) OR (cuc ban)) ((anh de) or (hanh de)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang x hoi. hieu va pham ((chuc ban) OR (cuc ban)) ((anh de) OR (hanh de)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. hieu va pham ((chuc ban) OR (cuc ban)) ((anh de) or (hanh de)) cua te*".
