price
How much price ranking we want in serving results. Price reranking causes product items with a similar recommendation probability to be ordered by price, with the highest-priced items first. This setting could result in a decrease in click-through and conversion rates. Allowed values are: * no-price-reranking * low-price-reranking * medium-price-reranking * high-price-reranking If not specified, we choose default based on model type. Default value: no-price-reranking. Can only be set if solution_types is SOLUTION_TYPE_RECOMMENDATION.
