   - Admin > System > Search
   - Try searching by exact URL
2. Verify required fields are present:
   - `url`, `title`, `content`
3. Check crawler logs: `logs/fess-crawler.log`
4. Manually trigger re-indexing:
   - Admin > Scheduler
   - Run "Default Crawler" job

#### Issue: Authentication errors on API calls

**Solution**:
- Verify credentials: default is `admin`/`admin`

### Small Errors Automatically Handled { #small-errors-automatically-handled }

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

The client will get a **500 Internal Server Error** for that request, but the application will continue working for the next requests instead of just crashing completely.

    //
    // Except for (c), every thread should occupy the monitor very briefly, and every thread leaves
    // the monitor with the guard satisfied. Therefore as soon as tearDownLatch is triggered, we
    // should be able to enter the monitor, and then we set the guard to satisfied for the benefit
    // of any remaining waiting threads.

 *  **Forbid response bodies on HTTP 204 and 205 responses.** Webservers that
    return such malformed responses will now trigger a `ProtocolException` in
    the client.

 *  **WebSocketListener has incompatible changes.** The `onOpen()` method is now
    called on the reader thread, so implementations must return before further
