An online transaction platform implements searching for product information from a database according to category information. The products are categorized based on product attributes and sale attributes to obtain multiple product categories. The products under the same product category have same or substantially similar product attributes and sale attributes. One or more calculation algorithms may be applied to the products under each category respectively to calculate price information that corresponds to each product category. The price information refers to price information of the products under their corresponding sale attributes. The price information of the corresponding product category is displayed when a product keyword corresponding to the product category is received. The method and device described herein may improve the operation speed and performance of servers for the online transaction platform.
