1. A method for performing content-based indexing of a financial database, said method comprising: causing at least one memory device to store data representative of a plurality of potential financial object features, each feature representing a complex set of characteristics of the financial object useful to a financial professional; causing the at least one memory device to store a user preference including at least one of a past decision about a financial object and a preferred feature of a financial object; causing at least one processor to retrieve a database record containing time series data from the financial database; causing the at least one processor to apply a mathematical transform function to the time series data contained in the database record to generate transformed data; causing the at least one processor to operate with the at least one memory device to create an indexed database wherein any of the plurality of potential financial object features is usable as a query to search for such feature in different time series data sets by, for each of the plurality of potential financial object features: (i) causing the at least one processor to determine whether said potential financial object feature exists in at least one of the time series data and the transformed data, and (ii) if the determination is that said potential financial object feature exists in at least one of the time series data and the transformed data, causing the at least one memory device to store, in said indexed database, an indication of an association between that potential financial object feature and said data in which the feature exists; and causing the at least one processor to operate with at least one display device to display a subset of at least one of the time series data and the transformed data based on the user preference, the subset representing at least one stored feature that was found to exist in at least one of the time series data and the transformed data.
