1. A computer-implemented method for providing a query feedback to a user in an information retrieval system, comprising: receiving a query input from a user, said query comprising one or more terms representing one or more subjects of interest to the user, each of said one or more subjects having a search attribute corresponding to a first database; collecting data from a data source, said data having an attribute corresponding to a second database; associating said search attribute corresponding to the first database with said attribute corresponding to the second database of said data from said data source, wherein said attribute is not said search attribute; and executing the query input to generate a result based on said association, wherein the result comprises results from (a) querying the first database using said search attribute and a term from said one or more terms for said search attribute, and (b) querying the second database using said attribute and said term from said one or more terms for said search attribute.
