Abstract
In a method for a dynamic updating of an index of a search engine, wherein the index is an inverted index comprising a dictionary, a posting file with a posting list for each keyword of the index and a database log, the documents are inserted in the index in small batches called update generations, a list of all occurrences of keywords in the documents of each update generation is generated, the occurrence list is inserted in the database log, and for each keyword entered in the database a reference to a previous entry of the same keyword is created. This previous entry has a reference stored in the mass storage device as the last added entry of all recently keywords.—A search engine performing the method may be implemented on one or more servers with a mass storage device, and comprises a core search engine with a search subsystem and an indexing subsystem for creating a keyword index stored on the mass storage device and with the index realized as a dynamically updateable index.
