- Input validation using `validateInputStream()`

**Covered Extractors**:
- MsWordExtractor
- MsExcelExtractor
- MsPowerPointExtractor
- TextExtractor

**Test Count**: 8 tests

**Key Scenarios**:
- ✅ Successful extraction closes resources properly
- ✅ Failed extraction includes descriptive error messages
- ✅ Null input stream validation
- ✅ Error messages include file type context

- `CurlResponseTest`: Tests for response handling, status codes, content retrieval, resource management
- `CurlExceptionTest`: Tests for exception handling and error scenarios

 *
 * <p>The job supports selective crawling by specifying configuration IDs for different
 * types of crawlers (web, file, data). It manages the crawler process lifecycle,
 * handles timeout scenarios, and ensures proper cleanup of resources.</p>
 *
 * <p>Key features:</p>
 * <ul>
 *   <li>Concurrent crawler process management with configurable limits</li>
 *   <li>Selective crawling based on configuration IDs</li>

**Configuration**: Set `web.api.gsa=true` in `system.properties` to enable GSA compatibility features.

For most migration scenarios, we recommend using the modern JSON Search API (`/api/v1/documents`) instead.

### Admin APIs

All admin APIs require authentication (`-u admin:admin` or Bearer token).

**Base Path**: `/api/admin/`

 * using the Apache Tika library. It extends {@link PasswordBasedExtractor} to handle password-protected files.

 * This class provides methods to extract text from an input stream, handling different scenarios such as:

 * <ul>
 *   <li>Normalizing text content</li>
 *   <li>Handling resource names and content types</li>
 *   <li>Retrying extraction without resource name or content type if the initial attempt fails</li>
