Struct EnsembleRetriever 

Source 
pub struct EnsembleRetriever { /* private fields */ }
Expand description

A retriever that combines results from multiple retrievers using Reciprocal Rank Fusion (RRF) with configurable weights.

Implementations§

Source§

impl EnsembleRetriever

Source

pub fn new(retrievers: Vec<(Arc<dyn Retriever>, f64)>) -> Self

Create a new EnsembleRetriever with weighted retrievers.

Each tuple is (retriever, weight). The weight scales the RRF score contribution of that retriever.
