• Performing a fuzzy search may retrieve terms with similar spellings: (("chua hay la.") OR ((("chua thay lam.") OR ("chua thay vam."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"chua hay la.\") OR (((\"chua thay lam.\") OR (\"chua thay vam.\"))))".
• Removing quotes may allow a broader search: (( chua hay la. ) OR ((( chua thay lam. ) OR ( chua thay vam. )))).
• Adding a wildcard symbol may retrieve word variants: (("chua hay la.") OR ((("chua thay lam.") OR ("chua thay vam."))))*.
