1. One or more computer-storage media storing computer-useable instructions that, when used by a computing device, cause the computing device to perform a method for utilizing a hybrid-distribution system for identifying relevant documents based on a search query, the method comprising: allocating a group of documents to a segment, the group of documents being indexed by atom in a reverse index and indexed by document in a forward index; storing a different portion of the reverse index and the forward index on each of a plurality of nodes that form the segment; accessing the reverse index portion stored on each of a first set of nodes to identify a first set of documents that is relevant to the search query; and based on document identifications associated with the first set of documents, accessing the forward index portion stored on each of a second set of nodes to limit a quantity of relevant documents in the first set of documents to a second set of documents.
