## 시작하기

Fess를 사용해보는 방법은 두 가지가 있습니다. 첫 번째는 직접 다운로드하여 설치하는 방법이며, 두 번째는 [Docker](https://www.docker.com/products/docker-engine)를 사용하는 방법입니다.

### 다운로드 및 설치/실행

Fess 14.17이 현재 사용 가능하며, [릴리스 페이지](https://github.com/codelibs/fess/releases "download")에서 다운로드할 수 있습니다. 다운로드는 deb, rpm, zip의 세 가지 형식으로 제공됩니다.

다음 명령은 zip 다운로드 사용 방법을 보여줍니다:

		n := len(strings.TrimRight(s[:len(b)-1], "/"))
		b[n] = 0 // Replace trailing slash with NUL terminator
	}
}

// fitsInBase256 reports whether x can be encoded into n bytes using base-256
// encoding. Unlike octal encoding, base-256 encoding does not require that the
// string ends with a NUL character. Thus, all n bytes are available for output.
//
// If operating in binary mode, this assumes strict GNU binary mode; which means

      value: Any,
    ) = apply {
      headers.add(name, value.toString())
    }

    /**
     * Adds a new header with the name and value. This may be used to add multiple headers with the
     * same name. Unlike [addHeader] this does not validate the name and
     * value.
     */
    fun addHeaderLenient(
      name: String,
      value: Any,
    ) = apply {
      addHeaderLenient(headers, name, value.toString())

 * </ul>
 *
 * <p>If your values may be zero, negative, or outside the range of an int, you may wish to use
 * {@link com.google.common.util.concurrent.AtomicLongMap} instead. Note, however, that unlike
 * {@code Multiset}, {@code AtomicLongMap} does not automatically remove zeros.
 *
 * <p>See the Guava User Guide article on <a href=

	for _, target := range targetList {
		if tgts[target.ID().ID] {
			// When target set should be online
			yes, err := target.IsActive()
			if err == nil && !yes {
				err = ErrTargetsOffline
			}
			if err != nil {
				return fmt.Errorf("error (%s): %w", target.ID(), err)
			}
		} else {
			// Just for call init.
			// Ignore target is online or offline
			_, _ = target.IsActive()
		}
	}

	return nil
}

In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

Handlers should remain backwards compatible. If a breaking API change is required, a new handler ID should be created.

## Setup & Configuration

 * {@link com.google.common.collect.Multiset} such as {@link
 * com.google.common.collect.ConcurrentHashMultiset} instead.
 *
 * <p><b>Warning:</b> Unlike {@code Multiset}, entries whose values are zero are not automatically
 * removed from the map. Instead they must be removed manually with {@link #removeAllZeros}.

 * implicit target of the methods {@link #peek()}, {@link #poll()} and {@link #remove()} -- is
 * defined as the <i>least</i> element in the queue according to the queue's comparator. But unlike
 * a regular priority queue, the methods {@link #peekLast}, {@link #pollLast} and {@link
 * #removeLast} are also provided, to act on the <i>greatest</i> element in the queue instead.
