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