Remarks
Sets property weights by schema type and property path. Property weights are used to promote and demote query term matches within a GenericDocument property when applying scoring. Property weights must be positive values (greater than 0). A property's weight is multiplied with that property's scoring contribution. This means weights set between 0.0 and 1.0 demote scoring contributions by a term match within the property. Weights set above 1.0 promote scoring contributions by a term match within the property. Properties that exist in the AppSearchSchema, but do not have a weight explicitly set will be given a default weight of 1.0. Weights set for property paths that do not exist in the AppSearchSchema will be discarded and not affect scoring. NOTE: Property weights only affect scoring for query-dependent scoring strategies, such as SearchSpec.RANKING_STRATEGY_RELEVANCE_SCORE.
