Abstract: A resilient query is provided that is used to search for a desired element in a similar document. A set of stable elements is predetermined or chosen and an original sequence of elements representing an ordered list of elements in an original document is generated. The original sequence of elements is then used in searching for a desired element in a similar document. A second sequence of elements is built from the similar document and compared to the original sequence. From the comparison, the desired element is determined.

Abstract: A method for managing a plurality of servers includes launching a cluster manger in response to a request from a user. The cluster manager is operable to manage system preference settings of a plurality of servers in a cluster group. A first server is selected from the plurality of servers provided in the cluster group according to an input from the user. The selected first server is designated to be a master server. A new system preference setting for the first server is receiving from the user. A second server from the plurality of server provided in the cluster group is selected according to an input from the user.
