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