Application ID: 14815880

Base Claim:
1. A method, comprising: generating, at a master node, configuration data for each indexer of a cluster of indexers under coordination by the master node, wherein the cluster of indexers is distributed across one or more sites, wherein configuration data for a particular indexer of the cluster of indexers indicates whether the particular indexer is a primary indexer with primary responsibility for responding to search queries originating from one or more search heads, wherein each of the one or more sites comprises a plurality of indexers of the cluster, wherein each indexer is operable to store multiple subsets of searchable data, and wherein each subset of searchable data is operable to be replicated across multiple indexers at the one or more sites, and wherein, in response to a search query, each indexer is configured to use configuration data received from the master node to search associated subsets of searchable data for which it has primary responsibility; sending, to each indexer of the cluster of indexers, configuration data generated for a respective indexer, wherein the configuration data further indicates whether a particular indexer is a secondary indexer with secondary responsibility for responding to the search queries related to searchable data replicated between the primary indexer and the secondary indexer.

Claim 12:
12. The method of claim 1 , further comprising: receiving, from a particular indexer of the cluster of indexers, a registration for one or more new subsets of data; selecting, by the master node, a set of peer indexers of the cluster of indexers based on a user-specified indexer replication factor indicating a number of separate indexers at which each subset of data of the one or more new subsets of data is to be stored; sending the replication instructions to the particular indexer.
