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