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