The present invention provides a system and method for controlling review of large documents. Purchasers who use computers to place orders may review a subset of selected items within the orders to ease review. The system may detect orders having items that exceed a specified threshold. The system may allow an operator to search for a subset of one or more items to review if the number of items exceeds the threshold. For example, an operator may search for a particular product using a product code or may search for a group of products using search terms. The system will then display the search results, rather than the entire order. The system may display the specified threshold number of items, if the search results exceeds the threshold. Thus, the system eases navigation within large documents, such as purchase orders and other sales documents that may contain many line items.
