FunctionScore

Models the search-time FunctionScore message: a set of scoring Functions (e.g. boost rankers) plus score-option params such as boost_mode and function_mode. Pass it to a search option via WithFunctionScore().

type FunctionScore struct {
    Functions []*Function
    Params    map[string]string
}

CONSTRUCTORS:

• NewFunctionScore()

  Creates an empty FunctionScore.

BUILDER METHODS:

• AddFunction(f *[Function](Function.md)) *FunctionScore

  Appends a scoring function to the score.

• WithParam(key string, value any) *FunctionScore

  Sets a score-option parameter key-value pair, converting the value to its string representation.

METHODS:

• Clone() *FunctionScore

  Returns a deep copy of the score: functions and params are copied so the returned score does not share mutable state with the source.

• ProtoMessage() *schemapb.FunctionScore

  Returns the corresponding protobuf FunctionScore message.

• ReadProto(p *schemapb.FunctionScore) *FunctionScore

  Parses a protobuf FunctionScore into the struct.
