Application ID: 10922694

Base Claim:
1. A method for distributing content indices for content corpora, the method comprising: analyzing search queries and partitioning individual terms in the search queries into sets based on co-occurrence of the individual terms within the search queries, wherein co-occurrence of given ones of the individual terms in a particular one of the search queries comprises the given individual terms co-occurring in a particular search query; mapping different ones of said sets to different server nodes; at said different server nodes, storing linking indices for the individual terms within the sets that have been mapped to said different server nodes; representing the individual terms of the search queries as nodes within a construct, with edges connecting the nodes, wherein each edge of the edges is assigned a frequency weight for representing co-occurrence in a corresponding search query of the individual terms represented by the nodes connected by a corresponding edge; maintaining a map indicating which of the server nodes store corresponding ones of the linking indices for the individual terms; and distributing the individual terms in a new query to the server nodes based on the map.

Claim 5:
5. The method as set forth in claim 1 wherein said analyzing comprises: constructing a graph in which the terms are represented as nodes and edges connect the nodes, each of the edges representing a frequency of co-occurrence of the terms represented by the nodes connected by the corresponding edge; and partitioning the graph to form the sets.
