* to be the case). Thus, this test is more of a regression test.
     *
     * Rough instructions to regenerate the test outputs and verify correctness:
     * - Temporarily change this test:
     * --- Comment out assertEquals.
     * --- System.out.println(input + " " + simplifyPath(input));
     * --- fail(). (If the test were to pass, its output would be hidden.)
     * - Run the test.

### Testing

The project uses JUnit 4 with embedded OpenSearch for integration testing:

```bash
# Run all tests
mvn test

# Run specific test class
mvn test -Dtest=SuggesterTest

# Run with verbose output
