12. The system of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to perform the method further comprising: sorting the one or more matched fields according to the determined aggregate weights; at least partially forming one or more search tables corresponding to the one or more search values; and at least partially forming one or more base tables corresponding to the one or more fields of the plurality of records of the linked hierarchical database; and wherein the merging, based at least in part on determining the aggregate weights, comprises combining at least a portion of the one or more search tables and the one or more base tables to form the merged table; and wherein the one or more search tables comprise zero or more common fields, and wherein the one or more base tables comprise zero or more common fields, and wherein the one or more base tables comprise record identifiers for each entity in the hierarchy.

The system of claim 12 , wherein at least partially forming the one or more base tables comprises at least partially forming tables having multiple fields and wherein the base tables comprise record identifiers for each entity in the hierarchy and wherein the method further comprises sorting each entity in the hierarchy by an associated hierarchy level, wherein the sorting each entity in the hierarchy by the associated hierarchy level comprises progressively sorting each entity in the hierarchy by each hierarchy level from a highest level to a lowest level in the hierarchy.
