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