### Index from Existing Documents

```java
import org.codelibs.fess.suggest.index.contents.document.ESSourceReader;

// Index suggestions from existing Elasticsearch documents
DocumentReader reader = new ESSourceReader(
    client,
    suggester.settings(),
    "content-index",        // source index
    "document"             // document type
);

suggester.indexer()

/** A basic HTTP/2 server that serves the contents of a local directory.  */
class Http2Server(
  private val baseDirectory: File,
  private val sslSocketFactory: SSLSocketFactory,
) : Http2Connection.Listener() {
  private fun run() {

    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again.
* `close()`: Closes the file.

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:

```Python
contents = await myfile.read()
```

import org.apache.maven.api.annotations.Nullable;

/**

 * backing store (e.g. file system, database, memory).
 * <p>
 * This is mainly used to parse files into objects such as Maven projects,
 * models, settings, or toolchains. The source implementation handles
 * all the details of accessing the underlying content while providing
 * a uniform API to consumers.
 * <p>

    copyTo(Funnels.asOutputStream(hasher));
    return hasher.hash();
  }

  /**
   * Checks that the contents of this byte source are equal to the contents of the given byte
   * source.
   *
   * @throws IOException if an I/O error occurs while reading from this source or {@code other}
   */
  public boolean contentEquals(ByteSource other) throws IOException {
    checkNotNull(other);

                () -> assertEquals(6118, WinError.ERROR_NO_BROWSER_SERVERS_FOUND));
    }

    @Test
    @DisplayName("Arrays: non-null, same length, and exact contents")
    void arrays_are_well_formed_and_match() {
        // Validate arrays existence and alignment (edge and structure checks)
        assertNotNull(WinError.WINERR_CODES, "WINERR_CODES should not be null");
