Here, the types corresponding to the age a, the date B, and the license plate number C are an age type, a date type, and a license plate number type, respectively. Nodes corresponding to the types can be determined from the xml documents, and then the target regular expression corresponding to the key words is determined from the determined nodes. By means of the step-by-step determination mode, the efficiency of determining the target regular expression can be improved, and further the searching efficiency is improved.
As shown in fig. 2, an embodiment of the present invention provides a search method applied to a search engine, where the method may include the following steps:
