What happened

构建社区摘要时（community_store.py中的build_communities方法），先清空向量存储，仅提供了ChromaStore对于实现truncate方法，未提供MilvusStore对于该方法的实现，当使用milvus作为向量数据库时会抛出错误“NotImplementedError”

What you expected to happen

提供一种实现

def truncate(self):
        """Drop milvus collection.
        """
        logger.info(f"begin truncate milvus collection:{self.collection_name}")
        from pymilvus import utility
        if utility.has_collection(self.collection_name):
            utility.drop_collection(self.collection_name)

        logger.info(
            f"truncate milvus collection {self.collection_name} success"
        )

I guess it's because my account doesn't have the permission to push code？
