Embodiment Construction
[0029] The present invention mainly proposes an improved method for existing document full-text search engines that do not support transactions, such as figure 1 As shown, the main logic is realized by the index management module 110; figure 2 It is a schematic diagram of the detailed implementation of key modules in index management, including:
[0030] Index read-write interface 210: accept and execute application read-write requests. For read requests, the index interface combines the search result information returned by the Index Reader index read interface 225 and the cloud index interface 240, and then filters through the index filter 230 to filter out the The deleted document is returned to the application service; for the write request, if it is an add operation, then directly write the data into the current transaction index file 270, if it is a modification operation, the index interface is converted into a two-step operation, and the first step will be modified T...
