• Performing a fuzzy search may retrieve terms with similar spellings: "(estudios OR estudio) de derecho (intern" OR ((interneta" OR internoeta") OR internoet"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(estudios OR estudio) de derecho (intern\" OR ((interneta\" OR internoeta\") OR internoet\"))".
• Removing quotes may allow a broader search: (estudios OR estudio) de derecho (intern OR ((interneta OR internoeta ) OR internoet )).
• Adding a wildcard symbol may retrieve word variants: "(estudios OR estudio) de derecho (intern" OR ((interneta" OR internoeta") OR internoet"))*.
