• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((lanh y) or (hanh y)) ((sang ma) OR (sang tao)) hoi. hieu ve cao duc van anh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((lanh y) OR (hanh y)) ((sang ma) OR (sang tao)) hoi. hieu ve cao duc van anh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((lanh y) or (hanh y)) ((sang ma) OR (sang tao)) hoi. hieu ve cao duc van anh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: thuat ((lanh y) or (hanh y)) ((sang ma) OR (sang tao)) hoi. hieu ve cao duc van anh vai cua tre*.
