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