• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach thu) OR (sach thue)) ((nang xa) or (lang xa)) hoi. thien van pham duc van hang di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach thue)) ((nang xa) OR (lang xa)) hoi. thien van pham duc van hang di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) OR (sach thue)) ((nang xa) or (lang xa)) hoi. thien van pham duc van hang di cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach thu) OR (sach thue)) ((nang xa) or (lang xa)) hoi. thien van pham duc van hang di cuu tre*.
