Abstract: A storage stores a classified-component-presence region where a component is present which constitutes one or more items of content while associating the classified-component-presence region with the respective one of the items of content. An acquisition controller acquires designation data designating a second region which is present around a first region equivalent to the classified-component-presence region of an item of content to be searched for and limits a likelihood of presence of the component. A search controller searches the item of content to be searched for from those stored in the storage based on the designation data. A display controller displays a search result on a display.
