• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programable plc codigo.\"))) OR (\"programaaas de codigo.\"))~".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programable plc codigo. ))) OR ( programaaas de codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programable plc codigo."))) OR ("programaaas de codigo."))*.
