The invention is directed to a system and a method for where-used searches in a hierarchical database. Unlike database systems in prior art, the invention allows fast, efficient and convenient where-used search for data with multiple revisions in a multi-level hierarchical database. Specifically, the invention is directed to a system for and method of searching for data in a multi-level hierarchical database coupled with a search engine. The invention allows not only direct where-used searches in a multi-level hierarchical database for modified objects in a hierarchical database but also indirect where-used searches for a target object or objects that are modified directly by a user or that are modified indirectly due to modifications of an object and objects with a higher hierarchy than the target object or objects.
