• Performing a fuzzy search may retrieve terms with similar spellings: (("ngan sach tham nuoc.") OR ((("ngan sach tai nuoc.") OR ("ngan lich tai nuoc."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ngan sach tham nuoc.\") OR (((\"ngan sach tai nuoc.\") OR (\"ngan lich tai nuoc.\"))))".
• Removing quotes may allow a broader search: (( ngan sach tham nuoc. ) OR ((( ngan sach tai nuoc. ) OR ( ngan lich tai nuoc. )))).
• Adding a wildcard symbol may retrieve word variants: (("ngan sach tham nuoc.") OR ((("ngan sach tai nuoc.") OR ("ngan lich tai nuoc."))))*.
