Search Computing (SeCo) aims at building applications that bridge the gap between traditional and vertical search engines, by answering to queries over multiple domains, like "Find a good Jazz concert close to a specified location, a good restaurant and an hotel at ". We demonstrate the Liquid Query (LQ) interface for multi-domain search, which enables the formulation of conjunctive queries over multiple Web data sources, wrapped as search services and connected by access paths. LQ supports the iteration over query formulation, result visualization and query refinement, with commands for perusing the result set, changing the visualization of data based on their type (e.g., geographical or temporal) and interacting with the remote search services. It also supports an exploratory search approach, where the user starts by accessing one data source, to be then assisted in progressively joining other correlated sources in an interactive exploration of the search space.
