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