Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating search query metadata for a graph search query for use in selecting web pages relevant to the graph search query. In one aspect, a method includes receiving a graph search query specifying user-selected graph search elements; generating graph search query metadata representing the graph search elements of the graph search query and relationships of the graph search elements; comparing the graph search query metadata to content metadata sets, wherein each content metadata set represents content elements of a content item presented on a respective web resource and relationships of the content elements; determining similarity scores between the content metadata sets and the graph search query metadata based on the comparison; and selecting web resources on which the content items are presented based on the similarity scores of the respective content metadata sets.
