摘要:
Upon reception of a retrieval request containing a retrieval key word from a client, a business flow registration information table is searched based on the retrieval key word to acquire a flow ID and a node ID of a business flow containing the retrieval key word. The flow ID and the node ID acquired are stored in a retrieval result table. With reference to a business flow operation history table, the node use count of the acquired node ID is divided by the flow use count of the acquired flow ID to calculate a node pass ratio. The calculated node pass ratio is stored in a node pass ratio table. With the node pass ratio as a score, the node pass ratio information is sorted in the descending order of the score. The retrieval request display data is generated in the order of sorting, and sent to the client.
