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