```mermaid

Understanding --> BM25
|
||
Understanding --> Vector
|

Understanding --> Graph
|

Reranker --> Compression

```
|

|
||
## 检索
|
||
|
||
采用 Hybrid Retrieval：
|
||
|
||
- Keyword
|
||
- BM25
|
||
- Vector
|
||
- Graph
|
||
- Metadata Filter
|
||
|
||
最终通过 Reranker 与 Context Compression 提高上下文质量。
