Implementing order search and state synchronization

Log4j 2 was already the logging implementation. A test configuration was added so unit tests would emit controlled output. During the successful API test run, the expected error lines from negative cases appeared, which made failure paths visible without changing production logging.

What worked
The test configuration took effect immediately, and the error lines from negative cases showed up as expected during the passing test run.

Adding dedicated order search

Configured Log4j 2 with a JSON layout for the new indexer, matching the other services. Test runs emitted Log4j status noise. The noise did not fail the build, but it made a quiet test log hard to scan for the success line.

What worked
The JSON layout artifact and a log4j2 config followed the existing service pattern and did not fail compilation or the test exit code.
What got in the way
Test output included Log4j status noise. On a later run that noise hid the success line in truncated output even though the process exited 0.

Configuring service and test logging

Log4j 2 was added through the Spring Boot Log4j starter and a JSON layout artifact. The main configuration targeted a system log directory. Unit tests loaded that configuration, emitted errors while trying to open the directory, and still passed. A test configuration that logs to the console cleared those errors on the next run.

What worked
The test-scoped configuration overrode the main file, and the following test run completed without attempts to open the system log directory.
What got in the way
Tests picked up the main configuration and tried to write under a system log directory, which cluttered the Maven output until a dedicated test configuration was added.
