1. A system comprising: one or more processors; one or more memories storing program instructions that the one or more processors execute; computer usable program code stored in at least one of the memories, which when the computer usable program code is executed by the one or more processors the system is operable to receive a search query comprising of at least one search criteria, wherein the at least one search criteria is a text string; computer usable program code stored in at least one of the memories, which when the computer usable program code is executed by the one or more processors the system is operable to perform a keyword search against an standard index, wherein the standard index is comprised of keywords obtained from a document within a standard cluster, wherein the standard cluster is a document cluster sharing a plurality of keywords; computer usable program code stored in at least one of the memories, which when the computer usable program code is executed by the one or more processors the system is operable to execute an enhanced search against an enhanced index, wherein the enhanced index is comprised of metadata associated with an enhanced cluster, wherein the enhanced cluster is a document cluster associated with the metadata, wherein the metadata is a user defined metadata; computer usable program code stored in at least one of the memories, which when the computer usable program code is executed by the one or more processors the system is operable to aggregate the standard cluster and the enhanced cluster into separate merged documents, wherein the separate merged documents are documents comprising of the standard cluster and enhanced cluster contents; and computer usable program code stored in at least one of the memories, which when the computer usable program code is executed by the one or more processors the system is operable to execute a ranking algorithm on each separate merged document to obtain a final ranking of content within the single document, wherein the ranking algorithm applies a ranking formula, wherein the ranking formula comprises sum of product of a tag line presence value with a hit weight and product of a cluster rank with the hit weight subtracted from one.
