Graph Database Entities Not Utilized in Recall within

[pihang]

🐛 Describe the bug

memo/proxy/main.py
It seems that when answering questions in memo/proxy/main.py, the recall mechanism doesn't utilize the dictionary information from the graph database.

Current code:
memories_text = "\n".join(memory["memory"] for memory in relevant_memories["results"])

In memo/memory/main.py, the memory search actually includes parallel searches in both vector storage and graph storage. The code returns:
return {"results": original_memories, "relations": graph_entities}

However, here only original_memories from vector storage recall is handled, and the graph database entities (graph_entities) are not used in constructing the memory recall.

How should we handle the recall of entities from the graph database?

For instance, data structured as follows is not being utilized:
search_results.append({"source": item[0], "relationship": item[1], "target": item[2]})
Example:

{
  "memories": [...],
  "entities": [
    {"source": "peter", "relation": "identity", "destination": "spiderman"}
  ]
}
