Difference between search record and add search record?

When we mention a record name in the search record option in the component properties then the searching will take place from that record when the component search page appears. When we add a new value in the add mode, the record name that we specify in the add search record option the new value gets stored there. By default if we don’t mention any value in the add search record option then the new value will be stored in the table mentioned in the search record option
