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