• Performing a fuzzy search may retrieve terms with similar spellings: (("airports -- design and reconstruction.") or ((((("airports -- design and constitution.") OR ("airports -- design and institutions."))) or ("airports -- design and institution."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("airports -- design and reconstruction.") OR ((((("airports -- design and constitution.") OR ("airports -- design and institutions."))) OR ("airports -- design and institution.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"airports -- design and reconstruction.\") or (((((\"airports -- design and constitution.\") OR (\"airports -- design and institutions.\"))) or (\"airports -- design and institution.\"))))".
• Removing quotes may allow a broader search: (( airports -- design and reconstruction. ) or ((((( airports -- design and constitution. ) OR ( airports -- design and institutions. ))) or ( airports -- design and institution. )))).
• Adding a wildcard symbol may retrieve word variants: (("airports -- design and reconstruction.") or ((((("airports -- design and constitution.") OR ("airports -- design and institutions."))) or ("airports -- design and institution."))))*.
