What Is an Index Method?

In addition to storing the node information, an additional index table is also established to identify the address of the node. The index table consists of several index entries. If each node has an index entry in the index table, the index table is called a dense index. If a group of nodes corresponds to only one index entry in the index table, the index table becomes a sparse index. The general form of an index entry is usually a keyword or address. In search engines, you need to find records based on the value of certain keywords. For this purpose, you can index by keywords. This index is called an inverted index. This is called an inverted file. Inverted files can be retrieved quickly. This index storage method is currently the most commonly used storage method for search engines.
