Worked on the elastic/elasticsearch-java repository to enhance the developer experience by updating the logging configuration documentation for the Java REST 5 client. Focused on clarifying which class to use for enabling trace logging of requests and responses, the work provided precise, step-by-step instructions and concrete examples to help users activate detailed request logging. This documentation, written in Markdown, aimed to improve debuggability and reduce the time required to diagnose client application issues. The effort centered on documentation skills and did not involve bug fixes, but delivered a targeted feature that addressed a common pain point for Java client users.
