In one example of a search, for example, it is necessary to search all articles in the database that contain the word "safe". First, the conversion module 01 converts the input into a preset information format, i.e., to-be-retrieved information of a triplet (1, "safe", 0), and then transmits the information to the search module 02 for searching. In the searching module 02, firstly, it is analyzed that the content to be searched in the information to be searched in the preset information format is "safe", then the searching module 02 finds all article numbers containing "safe" in the database, and through matching, the query information in the preset information format transmitted by the searching module 02 is an information group (1, "1 #4# 7" and "3 #1# 2"), wherein the second part "1 #4# 7" indicates that the articles with numbers 1, 4 and 7 contain "safe", and "3 #1# 2" indicates that three articles respectively contain three, one and two "safe". The output module 03 analyzes and obtains the query result according to the query information (1, "1 #4# 7", "3 #1# 2") in the preset information format, first finds the corresponding articles according to "1 #4# 7", then sorts according to "3 #1# 2", sequentially presents the first article, the seventh article and the fourth article to the user, and completes the information retrieval process.

The preset information format may be a predetermined format that facilitates information stream transmission and analysis, and may define the type of information included in the preset information format, for example, the information in the preset information format may include main content of the information, may further include an identification code, and may even include user information. For example, the information to be retrieved in the preset information format may include content to be retrieved corresponding to the information to be retrieved, such as a retrieval key, a phrase, and the like, and may further include an identification code corresponding to the content to be retrieved, so that a retrieval result corresponding to the content to be retrieved is identified subsequently according to the identification code, and the information to be retrieved in the preset information format may further include user information corresponding to the content to be retrieved, that is, user information of the content to be retrieved is input, so that the retrieval result corresponding to the content to be retrieved is subsequently associated with the user.
Step S20, analyzing and acquiring the content to be retrieved in the information to be retrieved according to the information to be retrieved, searching and acquiring a query result in a predetermined database according to the analyzed content to be retrieved, and converting the query result into the query information in the preset information format;

In one example of a search, for example, it is necessary to search all articles in the database that contain the word "safe". First, the conversion module 01 converts the input into a preset information format, i.e., to-be-retrieved information of a triplet (1, "safe", 0), and then transmits the information to the search module 02 for searching. In the searching module 02, firstly, it is analyzed that the content to be searched in the information to be searched in the preset information format is "safe", then the searching module 02 finds all article numbers containing "safe" in the database, and through matching, the query information in the preset information format transmitted by the searching module 02 is an information group (1, "1 #4# 7" and "3 #1# 2"), wherein the second part "1 #4# 7" indicates that the articles with numbers 1, 4 and 7 contain "safe", and "3 #1# 2" indicates that three articles respectively contain three, one and two "safe". The output module 03 analyzes and obtains the query result according to the query information (1, "1 #4# 7", "3 #1# 2") in the preset information format, first finds the corresponding articles according to "1 #4# 7", then sorts according to "3 #1# 2", sequentially presents the first article, the seventh article and the fourth article to the user, and completes the information retrieval process.
