### collectionFilters \CollectionFilter>`} default={`defaultCollectionFilters`} /> Allows custom [CollectionFilter](/current/core/reference/typescript-api/configuration/collection-filter#collectionfilter)s to be defined. ### productVariantPriceSelectionStrategy \ProductVariantPriceSelectionStrategy`} default={`DefaultProductVariantPriceSelectionStrategy`} since="2.0.0" /> Defines the strategy used to select the price of a ProductVariant, based on factors such as the active Channel and active CurrencyCode. ### productVariantPriceCalculationStrategy \ProductVariantPriceCalculationStrategy`} default={`DefaultTaxCalculationStrategy`} /> Defines the strategy used for calculating the price of ProductVariants based on the Channel settings and active tax Zone. ### productVariantPriceUpdateStrategy \ProductVariantPriceUpdateStrategy`} default={`DefaultProductVariantPriceUpdateStrategy`} since="2.2.0" /> Defines the strategy which determines what happens to a ProductVariant's prices when one of the prices gets updated. For instance, this can be used to synchronize prices across multiple Channels. ### stockDisplayStrategy \StockDisplayStrategy`} default={`DefaultStockDisplayStrategy`} /> Defines how the `ProductVariant.stockLevel` value is obtained. It is usually not desirable to directly expose stock levels over a public API, as this could be considered a leak of sensitive information. However, the storefront will usually want to display *some* indication of whether a given ProductVariant is in stock. The default StockDisplayStrategy will display "IN\_STOCK", "OUT\_OF\_STOCK" or "LOW\_STOCK" rather than exposing the actual saleable stock level. ### stockLocationStrategy \StockLocationStrategy`} default={`DefaultStockLocationStrategy`} since="2.0.0" /> Defines the strategy used to determine which StockLocation should be used when performing stock operations such as allocating and releasing stock as well as determining the amount of stock available for sale.
