is known as a string, a desired file, or a mapping from a string to a file. They are the opposite. Therefore, if the index is always able to save the map from string to file, it will greatly improve the search speed. Since the mapping from string to file is the reverse process of file-to-string mapping, the index that holds this information is called a reverse index. The information stored in the reverse index is generally as follows: Let's say that there are 100 documents in my document collec
