In some embodiments, the first search formula includes, but is not limited to, a conventional search formula, an intelligent search formula, and the like, where the conventional search formula mainly identifies search contents input by a User, and is determined according to a recognition result, for example, the search contents input by the User are a certain patent application number, the network device obtains the applicant/inventor/agent corresponding to the patent application number, a citation/cited patent, a family of patents, determines a first search formula "applicant/User 1" according to the applicant User1 corresponding to the patent application number, then generates corresponding first search prompt information "same applicant User1 related patent quick search", and the intelligent search formula may be that one or more first documents are statistically analyzed to obtain all first documents or a plurality of first documents which are arranged in a predetermined number in front and occupy a plurality of comparison terms (for example, keywords, patent class numbers, applicant, and the like) and are ranked according to the patent application number, for example, performs statistical analysis on 100 first documents which are arranged in front and occupy a plurality of comparison terms corresponding to the relevance ranking, and wherein the first search terms corresponding to the first documents are not found by the first search formula 2, and the invention search formula may be a search algorithm is not limited to the first search formula 2, and the invention search algorithm is not limited to the first search algorithm is generated by adding the search results, and the first search formula may be the search algorithm is not limited to the method of adding the search results to the first search results, deleting, replacing, rearranging combinations, etc., and then generating a first search formula based on the adjusted search term, for example, the search content is "chinese library and air conditioner and bluetooth", and the first search formula is generated by replacing "chinese library" in the search content with "european library".

In step S12, the network device sends the at least one first search hint information to the user device. In some embodiments, the first search hint information may be sent to the user device separately, or may be sent to the user device together with one or more first documents. In some embodiments, the searching is performed according to the first searching formula, one or more second documents are obtained through searching, the one or more second documents are sent to the user equipment together with the first searching prompt information, or the one or more second documents are ranked according to the relevance with the searching condition or the first document or according to other factors (such as application date), the first searching prompt information is sent to the user equipment together with the first searching prompt information together with the first predetermined number of second documents ranked in front, or the second documents which have been browsed by the user history can be removed from the one or more second documents, and the removed one or more second documents are sent to the user equipment together with the first searching prompt information.

In some embodiments, search content input by a User is identified, one or more first search terms associated with the search content are determined according to the identification result, then one or more first search formulas are further determined according to the one or more first search terms, for example, when the search content input by the User is identified as the patent application number N1, the applicant User1 corresponding to the patent application number N1 can be used as the first search term, so that the first search formula "applicant/User 1" is determined. In some embodiments, statistical analysis may also be performed on one or more first documents to obtain all or more frequently occurring words (e.g., keywords, patent class numbers, applicant, etc.) that are dominant in a predetermined number of the first documents ranked by relevance, and then these words are used as first search terms, and then the first search expression is further determined according to the first search terms, for example, statistical analysis is performed on the first 100 first documents ranked by relevance to obtain inventor User2 that is more frequently found among them, so that "User2" is used as the first search term, and further the first search expression "inventor/User 2" is determined. In some embodiments, the first term is a keyword of a document search, e.g., inventor, applicant, attorney docket, patent citation, patent family, etc., and in some embodiments, the first term is a keyword of one or more first documents determined from the main content or core content of each first document, but not any one of the one or more first documents.
