JoinDocuments
class JoinDocuments(BaseComponent)
A node to join documents outputted by multiple retriever nodes.
The node allows multiple join modes:
- concatenate: combine the documents from multiple nodes. Any duplicate documents are discarded.
- merge: merge scores of documents from multiple nodes. Optionally, each input score can be given a different
weight
& atop_k
limit can be set. This mode can also be used for "reranking" retrieved documents.
__init__
| __init__(join_mode: str = "concatenate", weights: Optional[List[float]] = None, top_k_join: Optional[int] = None)
Arguments:
join_mode
:concatenate
to combine documents from multiple retrievers ormerge
to aggregate scores of individual documents.weights
: A node-wise list(length of list must be equal to the number of input nodes) of weights for adjusting document scores when using themerge
join_mode. By default, equal weight is given to each retriever score. This param is not compatible with theconcatenate
join_mode.top_k_join
: Limit documents to top_k based on the resulting scores of the join.
