• Removing quotes may allow a broader search: (( biblioteconomia y administracion local ; ) OR ((( biblioteconomia i administracion local ; ) OR ( biblioteconomia la administracio local ; ))))~.
• Adding a wildcard symbol may retrieve word variants: (("biblioteconomia y administracion local ;") OR ((("biblioteconomia i administracion local ;") OR ("biblioteconomia la administracio local ;"))))*.
