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