• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (thuat sach)) ly hang x ho. hieu van hoc ((luc va) OR (duc va)) danh vinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) ly hang x ho. hieu van hoc ((luc va) OR (duc va)) danh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (thuat sach)) ly hang x ho. hieu van hoc ((luc va) OR (duc va)) danh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (thuat sach)) ly hang x ho. hieu van hoc ((luc va) OR (duc va)) danh vinh cuu tre*.
