1. A computerized method for performing a scholarly search using a processing server, said method comprises: processing, by a processing module in said processing server, a search query to identify at least one of a keyword; identifying, by a search tool in said processing server, at least one of a class and subclass corresponding to said identified keyword; fetching, by said search tool in said processing server, additional words from a dictionary that matches at least one of said identified class, subclass and keyword; framing, by said search tool in said processing server, a key string by combining at least one of said identified keywords and said fetched additional words; searching, by said search tool in said processing server, in at least one of a plurality of databases using said framed key string, wherein said search is performed by constructing a nucleus for said search query and matching said nucleus with those associated with existing categories in said plurality of databases, wherein said nucleus of existing categories in said plurality of databases is a pre-defined structure defined to represent a category including data on commercial viability and one or more of: words having positive association with the category, words negatively associated with the category, phrases or groups of loosely coupled words that are positively associated with the category, phrases or group of loosely coupled words that are negatively associated with the category, level of appropriateness of a document, type of subject matter, meta data derived from user preferences for user specific refinement of search results; and sending one or more search results from among patent documents, academic publications, and working papers by said processing server for display on the user device from which the search request was received, wherein commercial viability related to a category is determined by a commercialization evaluator module by automatically analyzing activity in the category and comparing said activity level against a pre-defined threshold.
