Assembly

Reciprocal Rank Fusion (RRF) query that merges result lists from multiple child queries without requiring score normalisation.

Score formula: score(d) = Σ 1/(k + rank_i(d)) where k defaults to 60.

RrfQuery(int)

Initialises a new RrfQuery with the given rank constant.

Field

Gets the primary field this query targets.

K

The ranking constant k. Higher values reduce the impact of top-ranked results. Default: 60.

Queries

The child queries whose result lists will be fused.

Add(Query)

Adds a child query whose results will be fused. Returns this for chaining.

Combine(TopDocs[], int, int)

Combines multiple TopDocs result sets using RRF scoring.

Equals(object?)

Determines whether the specified object is equal to the current object.

GetHashCode()

Serves as the default hash function.
