**Step 2: Transform to Fess Format**

Create a transformation script to map Solr fields to Fess fields:

```python
import json

# Load Solr export
with open('solr-export.json', 'r') as f:
    solr_data = json.load(f)

# Transform documents
fess_docs = []
for doc in solr_data['response']['docs']:
    fess_doc = {
        "url": doc.get("id", ""),

        configHelper.setLoadCallback(() -> -1);
        assertEquals(-1, configHelper.load());
    }

    static class TestConfigHelper extends AbstractConfigHelper {

        private final AtomicInteger loadCallCount = new AtomicInteger(0);
        private LoadCallback loadCallback = () -> 0;

        @Override
        public int load() {
            loadCallCount.incrementAndGet();
