description: Preserve unique source entries in search results to maintain proper citation tracking
globs: ['**/connector_service.py', '**/search_service.py']
alwaysApply: true
```

Search result processing should preserve all source entries to maintain accurate citation tracking, rather than deduplicating sources.

❌ Bad - Deduplicating sources:
```python
mapped_sources = {}
for chunk in chunks:
    source_key = chunk.get('url') or chunk.get('title')
    if source_key not in mapped_sources:
        mapped_sources[source_key] = create_source(chunk)
sources_list = list(mapped_sources.values())
```

✅ Good - Preserving unique sources:
```python
sources_list = []
for chunk in chunks:
    source = create_source(chunk)
    sources_list.append(source)
```

Each chunk should maintain its unique source reference for proper citation tracking.
