• Performing a fuzzy search may retrieve terms with similar spellings: (("thi o muong xay.") OR ((((("thi o muong xa.") OR ("thi _ muong xa."))) OR ("chi o muong xa."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thi o muong xay.\") OR (((((\"thi o muong xa.\") OR (\"thi _ muong xa.\"))) OR (\"chi o muong xa.\"))))".
• Removing quotes may allow a broader search: (( thi o muong xay. ) OR ((((( thi o muong xa. ) OR ( thi _ muong xa. ))) OR ( chi o muong xa. )))).
• Adding a wildcard symbol may retrieve word variants: (("thi o muong xay.") OR ((((("thi o muong xa.") OR ("thi _ muong xa."))) OR ("chi o muong xa."))))*.
