For migrating from Apache Solr:

#### Document Export and Import

**Step 1: Export from Solr**

```bash
# Export Solr documents as JSON
curl "http://solr-server:8983/solr/collection1/select?q=*:*&rows=10000&wt=json" \
  -o solr-export.json
```

**Step 2: Transform to Fess Format**

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

```python
import json

# Load Solr export

    settings1[Settings.HEADER_TABLE_SIZE] = 10000
    settings1[Settings.INITIAL_WINDOW_SIZE] = 20000
    settings1[Settings.MAX_FRAME_SIZE] = 30000
    peer.sendFrame().settings(settings1)
    peer.acceptFrame() // ACK SETTINGS
    val settings2 = Settings()
    settings2[Settings.INITIAL_WINDOW_SIZE] = 40000
    settings2[Settings.MAX_FRAME_SIZE] = 50000
    settings2[Settings.MAX_CONCURRENT_STREAMS] = 60000
