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