The electronic document is easy to lose the original document directory structure, and the actual application capability and the look-up experience of the original electronic document are reduced.

Which is not conducive to the storage and presentation of electronic documents that are partially unrelated to the component.

Conventional search method

At present, the main retrieval method of electronic documents based on bridge member maintenance is document name keyword retrieval. Collecting the stored electronic document names, analyzing the keyword preset index library in all the document names, receiving the keyword search request of the user, and returning the corresponding electronic document.

The keyword retrieval of the electronic document name is characterized by simple logic. However, in practical application, the matching degree between the keywords for retrieval and the keyword preset index library is low, the retrieval result is not accurate, the required electronic documents can be obtained only by manual screening, and the retrieval efficiency is low.

In summary, the invention mainly solves the problems that:

the electronic document is coupled with the component, the document structure is fixed, the adjustment flexibility is low, and the modification workload is large;

the electronic document has large storage volume and low loading speed;

the directory structure of the original electronic document is lost, and the actual application capability of the original electronic document is reduced;

the electronic documents are mainly searched by keywords, and the accuracy is low.
