- **License**: Apache 2.0
- **DI**: LastaFlute DI
- **Repo**: https://github.com/codelibs/fess-crawler

### Tech Stack

- **HTTP**: Apache HttpComponents 4.5+ and 5.x (switchable)
- **Extraction**: Apache Tika, POI, PDFBox
- **Testing**: JUnit 4, UTFlute, Mockito, Testcontainers
- **Storage**: In-memory (default), OpenSearch (optional)
- **Cloud**: AWS SDK v2 (S3), Google Cloud Storage

### Protocols

    public Logger getLogger() {
        return logger;
    }

    /**
     * Gets the appropriate extractor for the given response data.
     * Selects an extractor based on the MIME type or falls back to the Tika extractor.
     *
     * @param responseData the response data containing the document to extract
     * @return the extractor instance for processing the document

        try (InputStream is = new ByteArrayInputStream(SQL_REM_CONTENT.getBytes(StandardCharsets.UTF_8))) {
            final String contentType = mimeTypeHelper.getContentType(is, "test.sql");
            // Without override, Tika detects based on content+filename
            assertNotNull(contentType);
        }
    }

    @Test
    public void test_init_nullConfig() throws IOException {

3. **Fallback**: English (from `fess_label.properties` and `fess_message.properties`)

### Document Language Detection

During crawling and indexing, Fess:

1. Detects language from document content using Apache Tika
2. Validates against `supported.languages` list
3. Creates language-specific fields (e.g., `content_ja`, `title_en`, `content_sv`)
4. Applies language-specific analyzers for better search results
