Fess basiert auf [OpenSearch](https://github.com/opensearch-project/OpenSearch), aber es ist kein Wissen oder Erfahrung mit OpenSearch erforderlich. Fess bietet eine einfach zu bedienende Administrations-GUI zur Konfiguration des Systems über Ihren Browser.

## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

1. **Query parameter**: `?browser_lang=[locale]` (highest priority)
2. **Browser header**: `Accept-Language` header
3. **Fallback**: English (from `fess_label.properties` and `fess_message.properties`)

### Document Language Detection

During crawling and indexing, Fess:

    assertFalse(Ascii.equalsIgnoreCase("@", "`"));
    assertFalse(Ascii.equalsIgnoreCase("[", "{"));
  }

  @GwtIncompatible // String.toUpperCase() has browser semantics
  public void testEqualsIgnoreCaseUnicodeEquivalence() {
    // Note that it's possible in future that the JDK's idea to toUpperCase() or equalsIgnoreCase()

Caching
=======

OkHttp implements an optional, off by default, Cache. OkHttp aims for RFC correct and
pragmatic caching behaviour, following common real-world browser like Firefox/Chrome and 
server behaviour when ambiguous.

# Basic Usage

```kotlin
  private val client: OkHttpClient = OkHttpClient.Builder()
      .cache(Cache(
          directory = File(application.cacheDir, "http_cache"),
          // $0.05 worth of phone storage in 2020

        continue;
      }
