The invention provides a method for storing inverted index based on an inverted file, the method comprising: creating an inverted file in a storage medium for storing the inverted index, the inverted file including a plurality of fixed-size index blocks, each of them including a plurality of fixed-size index units, wherein each index unit is used to store one piece of index information; and sequentially storing the index information related to each index item into the created inverted file, wherein the index information related to the same index item is stored in continuous blocks and the index units in each index block are only for storing index information related to the same index item. Since each index block is used only for storing index information related to the same index item, when performing operations on the index information in an index block, other index items are not affected, therefore, it is possible to on-line update index information in any index block.
