- 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`
- Check if API is enabled in `system.properties`

            crawler.setBackground(true);
            crawler.setThreadPriority(crawlerPriority);

            crawlerList.add(crawler);
            crawlerStatusList.add(Constants.READY);
