RankFusion<TResult, TNewResult>(IAggregateFluent, Dictionary<string, PipelineDefinition<TResult, TNewResult>>, Dictionary<string, double>, RankFusionOptions)

Appends a $rankFusion stage to the pipeline.

public static IAggregateFluent<TNewResult> RankFusion<TResult, TNewResult>(this IAggregateFluent<TResult> aggregate, Dictionary<string, PipelineDefinition<TResult, TNewResult>> pipelines, Dictionary<string, double> weights = null, RankFusionOptions<TNewResult> options = null)

Parameters

aggregate IAggregateFluent

The aggregate.

pipelines Dictionary<string, PipelineDefinition<TResult, TNewResult>>

The map of named pipelines whose results will be combined. The pipelines must operate on the same collection.

weights Dictionary<string, double>

The map of pipeline names to non-negative numerical weights determining result importance during combination. Default weight is 1 when unspecified.

options RankFusionOptions

The rankFusion options.

Returns

IAggregateFluent

The fluent aggregate interface.

Type Parameters

TResult

The type of the result.

TNewResult

The type of the new result.

RankFusion<TResult, TNewResult>(IAggregateFluent, PipelineDefinition<TResult, TNewResult>[], RankFusionOptions)

Appends a $rankFusion stage to the pipeline. Pipelines will be automatically named as "pipeline1", "pipeline2", etc.

public static IAggregateFluent<TNewResult> RankFusion<TResult, TNewResult>(this IAggregateFluent<TResult> aggregate, PipelineDefinition<TResult, TNewResult>[] pipelines, RankFusionOptions<TNewResult> options = null)

Parameters

aggregate IAggregateFluent

The aggregate.

pipelines PipelineDefinition<TResult, TNewResult>[]

The collection of pipelines whose results will be combined. The pipelines must operate on the same collection.

options RankFusionOptions

The rankFusion options.

Returns

IAggregateFluent

The fluent aggregate interface.

Type Parameters

TResult

The type of the result.

TNewResult

The type of the new result.

RankFusion<TResult, TNewResult>(IAggregateFluent, (PipelineDefinition<TResult, TNewResult>, double?)[], RankFusionOptions)

Appends a $rankFusion stage to the pipeline. Pipelines will be automatically named as "pipeline1", "pipeline2", etc.

public static IAggregateFluent<TNewResult> RankFusion<TResult, TNewResult>(this IAggregateFluent<TResult> aggregate, (PipelineDefinition<TResult, TNewResult>, double?)[] pipelinesWithWeights, RankFusionOptions<TNewResult> options = null)

Parameters

aggregate IAggregateFluent

The aggregate.

pipelinesWithWeights (PipelineDefinition<TResult, TNewResult>, double?)[]

The collection of tuples containing (pipeline, weight) pairs. The pipelines must operate on the same collection.

options RankFusionOptions

The rankFusion options.

Returns

IAggregateFluent

The fluent aggregate interface.

Type Parameters

TResult

The type of the result.

TNewResult

The type of the new result.
