An object oriented search mechanism extracts structural metadata and data based on type of document contents and data sources connected to the documents. Relationships between textual and non-textual elements within documents as well as metadata associated with the elements and data sources are utilized to generate a unified object model with the addition of semantic information derived from metadata and taxonomy, which are used to enhance search indexing, ranking of search results, and dynamic adjustment of result rendering user interface with fine tuned relevancy. Additional data from data sources connected to the documents may also be used to unlock hidden data such as data that has been filtered out in an original document.
