#### Issue: Imported documents not appearing in search

**Solution**:
1. Check if documents were indexed:
   - 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
