description A method and apparatus for propagating updates in databases are disclosed. For example, the present method uses "blocking" and/or "thresholding" to delay update propagation and/or to limit the propagation of updates to an optimal stage. For example, the present method receives at least one database update and extracts at least one token from the at least one database update. The method then determines whether a threshold for propagating the at least one database update for the at least one token is reached. The method then propagates the at least one database update for updating an index structure of a database pertaining to the at least one token whose threshold has been reached.
