Abstract: A computer-implemented method for forming a search query includes receiving a search request for searching at least one output document based on a first input document, extract a first metadata from the first input document, a second metadata from at least one second input document, and a third metadata from synonyms of the first and second metadata, form a first set of metadata by combining the first, second and third metadata, rank a first set of categories, wherein a category associated with a highest number of input documents is ranked highest, forming a second set of categories by excluding a predefined number of categories, forming a second set of metadata by excluding at least one definition metadata from the first set of metadata, and forming a search query by combining the second set of metadata and second set of categories.
