Abstract
A method and system for expanding a template tree. A received search request includes (i) a search query and (ii) path information specifying at least one path of data nodes of the template tree. The template tree is a hierarchically organized data structure of data nodes. Each specified path in the path information includes a sequence of data nodes of the template tree. The data nodes in each sequence in each specified path are traversed. Each traversed data node that does not have a child node in the template tree is expanded to form in the template tree one or more child nodes corresponding to each expanded data node. Any other data node of the template tree is not expanded. Each formed one or more child nodes is instantiated with data values by retrieving the data values, in accordance with the search query, from at least one data source.
