#### Document Migration

**Step 1: Export from Source**

Export documents from your existing Elasticsearch/OpenSearch cluster:

```bash
# Using elasticdump
elasticdump \
  --input=http://old-es-server:9200/my-index \
  --output=documents.json \
  --type=data
```

**Step 2: Convert to Fess Format**

Transform documents to include Fess required fields. Example transformation script:

        final Map<String, Object> result = indexUpdater.ingest(accessResult, doc);

        assertNotNull(result);
        // Result should be the same as input doc when ingester is null or doesn't modify
        assertSame(doc, result);
    }

    // Test ingest with exception in ingester
    @Test
    public void test_ingest_withException() {

  }

  /**
   * Returns an immutable multimap containing the specified entries. The returned multimap iterates
   * over keys in the order they were first encountered in the input, and the values for each key
   * are iterated in the order they were encountered.
   *
   * @throws NullPointerException if any key, value, or entry is null
   * @since 19.0
   */

// If the content is valid JSON, the type will still be bytes.
func (v *Value) InferBytesType() (err error) {
	b, ok := v.ToBytes()
	if !ok {
		return fmt.Errorf("InferByteType: Input is not bytes, but %v", v.GetTypeString())
	}

	// Check for numeric inference
	if x, ok := v.bytesToInt(); ok {
		v.setInt(x)
		return nil
	}
	if x, ok := v.bytesToFloat(); ok {
		v.setFloat(x)

    }

    /**

     *
     * @param userMessage the user's message to wrap
