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