1. A method of storing and organizing information stored in at least one database by using a tree-structured index to find and retrieve stored objects having attributes similar to attributes of a target object to mine the at least one database for data leading to a prediction of a property of the target object, the at least one database being coupled to processor search manager apparatus, the processor search manager apparatus comprising a processor and memory, the method comprising inputting data describing attributes associated with at least two objects to the at least one database; storing said attribute data in at least one database and referencing this attribute data using a tree-structured index determined by multivariate statistical analysis; applying multivariate statistical analysis and clustering to said stored data and stored attribute data to determine an indexing and search method for indexing and searching said at least one database using said determined tree-structured index; using said indexing and search method to find and retrieve stored objects having attribute data similar to the attribute data of a target object; and applying at least one model to the attribute data of the retrieved stored objects to obtain a predicted property of the target object for output to an output device.
