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