The open-type abstract information includes: the related information aiming at giving users general understandings of the webpage content, as well as the information of the relation between the webpage content and users&#39; searches and queries. For example: besides ratings and comments, the information that helps users determine the correlation degree of the search, such as “pictures of the product”, “the price of the product”, “whether in stock”, etc., is also able to be added. Obviously, it should be understood that, in the embodiments of the invention, the expression form of the open-type abstract information is not limited. 
     The First Embodiment 
     Firstly, the method for a search engine to crawl the open-type abstract information of webpage is illustrated hereinafter, concretely it includes: when the webpage information is crawled, detecting whether a preset identification of open-type abstract information is included in the webpage information; and if it is detected that the identification is included in the webpage information, crawling a protocol header which describes the structure of the open-type abstract information in the webpage information and webpage content that maps to the structure described in the webpage information. 
     As shown in  FIG. 1 , it is a flow chart of the method  100  for a search engine to crawl the open-type abstract information of webpage in the embodiment of the invention, and the method  100  begins in step S 110 . In step S 110 , when the webpage information is crawled, detecting whether a preset identification of open-type abstract information is included in the webpage information. 
     Wherein, whether the open-type abstract information is included in the crawled webpage information is determined through the preset identification of open-type abstract information. In the embodiment of the invention, the concrete form of the above preset identification of open-type abstract information is not limited. 
     Optionally, in the embodiment of the present invention, each webpage may include at least one piece of open-type abstract information, and each piece of open-type abstract information is related to a keyword of the corresponding webpage. When the search keyword input by a user matches the keyword of a webpage, the search engine is able to return and display the open-type abstract information related to the keyword of the webpage. 
     Wherein, the format of the open-type abstract information may be HTML (Hypertext Markup Language), HTML5, JavaScript, Flash, or CSS (Cascading Style Sheet). It is understandable that in the embodiment of the invention, the concrete format of the open-type abstract information is not limited. 
     If it is detected that the identification is included in the webpage information, step S 130  is entered. In the step S 130 , the protocol header in the webpage information which describes the structure of the open-type abstract information and the webpage content mapped with the structure described in the webpage information are crawled. 
     Optionally, in the embodiment of the invention, the webpage content mapped with the structure described in the open-type abstract information includes at least one of the followings: text, picture, link, video and audio. It is understandable that in the embodiment of the invention, the concrete type of the webpage content is not limited.

     Optionally, in the embodiment of the invention, in step S 150 , the step of validating the format of the open-type abstract information includes: validating whether the size of the webpage area occupied by the open-type abstract information exceeds a predefined threshold value. 
     For example: the predefined threshold value is 400 px×170 px, and if the size of the webpage area occupied in the open-type abstract information exceeds 400 px×170 px, then the validation is not passed. It is understandable that in the embodiment of the invention, the concrete scope of the threshold value is not limited. 
     Optionally, in the embodiment of the invention, in step S 150 , the step of validating the content of the open-type abstract information includes: validating whether a specific element is included in the content of the open-type abstract information. Optionally, the specific element includes at least one of a price and a discount rate. 
     For example: if the content of the open-type abstract information includes the concrete price and/or the discount rate of a product or service, then the validation is not passed. Therefore, by the embodiment of the invention, the open-type abstract information provided by the search engine is able to provide only abstract content, not provide other possible meanings or behaviors, such as price competition, etc. It is understandable that in the embodiment of the invention, the concrete content of the specific elements is not limited. 
     Optionally, in the embodiment of the invention, if the validation in step S 150  is passed, step S 170  may be entered. 
     In step S 170 , if the validation is passed, when a search request matching the keyword of a webpage is received, the rendering result of rendering the open-type abstract information is returned according to the protocol header and the webpage content and the render result is taken as the search result of the search request.

     Optionally, in the embodiment of the invention, if the validation in step S 150  is not passed, step S 190  may be entered. 
     In step S 190 , when a search request matches the keyword of a webpage is received, default abstract information of the webpage is returned and taken as the search result of the search request. 
     Wherein, the above default abstract information may refer to the webpage abstract information crawled by adopting the Sitemap protocol, or the part which may be displayed after optimized in the webpage automatically recognized by the search engine. It is understandable that in the embodiment of the invention, the crawling mode of the default abstract information is not limited. 
     In the embodiment of the invention, when crawling the webpage information, when it is detected that the identification is included in the webpage information, it is capable to crawl the protocol header that describes the structure of the open-type abstract information in the webpage information and the webpage content that maps to the structure described in the open-type abstract information, thus facilitating to adjust the search engine to crawl the content of the open-type abstract information of webpage, greatly enriching the display forms of the abstract webpage information. 
     For example: assuming the webpage content that maps to the structure described in the open-type abstract information is text, the open-type abstract information includes: related information aiming at giving users general understandings of the webpage content, as well as the information of the relation between the webpage content and users&#39; searches and queries. For example: besides “ratings” and “comments”, the information that helps users determine the correlation degree of the search, such as “pictures of the product”, “the price of the product”, “whether in stock”, etc., are also able to be added. If a search engine understands the content in the webpage, it is capable to display the above search result in the search results according to the content. This search result is able to help search users have intuitive understandings of whether the site and the user&#39;s original search intentions are related and matching, thereby obtaining a higher click rate. 
     It should be noted that the method shown in  FIG. 1  is not limited to be carried out according to the shown order of the various steps, and the order of the various steps may be adjusted according to the need.
