US Patent 9727635 Combined code searching and automatic code navigation

Software code changes are facilitated by receiving as input a user query specifying a search term and automatically generating a ranked list of connected call trees based on the search term. Each connected call tree identifies subroutines that contain an identifier matching at least part of the search term or that are linked to a subroutine that contains an identifier matching at least part of the search term. The ranked list of connected call trees is displayed as a diagram.
