Design And Implementation Of SaaS Oriented Site Search Model

Site search engine as a search engine within the website platform, by analyzing the user input and retrieve the relevant data within the station,provides users of the platform a fast and convenient data access portal.The SaaS-based Web site often features multi-tenants, functional diversity,data diversity, and different user privilege levels. Through the design and implementation of SaaS-based site search model, not only can shorten the SaaS service provider development cycle, but also can customize the index rules according to the need, with flexibility and scalability. The author's lab is also developing and maintaining a SaaS-based CRM system. Therefore, the author studies and analyzes the current situation of the search engine development and the characteristics of SaaS model from the point of view of actual demand, and has planned the research content of this subject.In this topic, the author analyzes the implementation of traditional site search engine, and then put forward the direction of improvement. By analyzing the existing implementation of the existing search engine within the website platform, from the architectural level abstractly gives a complete site search engine should have what modules and the relationship among them. In this model, an index structure is designed to unify the structured and unstructured data of the SaaS platform. The interface that configures the relevant index rules is designed and implemented, which can be configured for the retrieval result interface. In addition, the other interfaces in the model are implemented and the SaaS-based site search model is applied to the existing laboratory platform. Through practical application, the feasibility of architecture and technology is verified. In the aspect of innovation, the author analyzes the traditional distributed indexing method and improves it on the basis of distributed B + tree method. A method of combining linear and B + tree is proposed. In the simulation experiment, the performance advantage of the method in retrieving efficiency and insertion efficiency is verified.
