### 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

        writeTestFile(content);

        // Reload the file
        protwordsFile.reload(null);

        PagingList<ProtwordsItem> list = protwordsFile.selectList(0, 100);

        // The file parsing may treat the escaped sequences differently
        // Check what we actually got
        assertTrue("Should have at least 3 items", list.size() >= 3);

        // Find and verify the expected items

        } else {
            cmdList.add("-Dfess.log.level=" + logLevel);
            if ("debug".equalsIgnoreCase(logLevel)) {
                cmdList.add("-Dorg.apache.tika.service.error.warn=true");
            }
        }
        stream(fessConfig.getJvmCrawlerOptionsAsArray())
                .of(stream -> stream.filter(StringUtil::isNotBlank).forEach(value -> cmdList.add(value)));
