What happens if a field extraction does not find a match for the defined values?

When a field extraction does not find a match for the defined values, the extraction still completes successfully. This behavior is designed to ensure that the search process is resilient and continues to function seamlessly, allowing for non-disruptive data processing and analysis.

In cases where there isn't a match, Splunk's extraction mechanism simply retains the record and indicates that the specific field will not be populated. This approach prevents interruptions or failures in the overall data extraction process, enabling users to work with partial data effectively.

The rationale behind this design is to allow searches to return relevant results even when some data points may not align with the extraction criteria, thus ensuring users can still derive insights from the available information without encountering disruptions.
