Abstract: Methods, systems, and computer programs are presented for providing a unified search tool for searching data in multiple domains. One method includes an operation for causing presentation of a user interface (UI) for entering one or more search parameters to search items in two or more domains. Each domain is owned by a different entity and data for each domain is acquired by the corresponding entity. Further, the method includes operations for receiving one or more search parameters values, searching, in response to the received search parameter values, the two or more domains based on the search parameters values, and ranking separately search results for each domain. Further, the method includes causing presentation in the UI of the search results for the two or more domains based on the ranking, the search results for each domain being presented in a separate results list.
