• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ty) OR (sach thu)) ((nang xa) or (lang xa)) hoi. lieu va pham duc van quang dien cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ty) OR (sach thu)) ((nang xa) OR (lang xa)) hoi. lieu va pham duc van quang dien cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ty) OR (sach thu)) ((nang xa) or (lang xa)) hoi. lieu va pham duc van quang dien cau tren".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ty) OR (sach thu)) ((nang xa) or (lang xa)) hoi. lieu va pham duc van quang dien cau tren*.
