• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ty) or (sach tu)) xang xa hoi. hieu van pham thuc va ((danh tu) OR (anh tu)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ty) OR (sach tu)) xang xa hoi. hieu van pham thuc va ((danh tu) OR (anh tu)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ty) or (sach tu)) xang xa hoi. hieu van pham thuc va ((danh tu) OR (anh tu)) cua te*".
