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