• Performing a fuzzy search may retrieve terms with similar spellings: (((("program _ codigo.") OR ("programaaaada dra codigo."))) OR ("programaaas a codigo."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programaaaada dra codigo.\"))) OR (\"programaaas a codigo.\"))".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programaaaada dra codigo. ))) OR ( programaaas a codigo. )).
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programaaaada dra codigo."))) OR ("programaaas a codigo."))*.
