Content returned by a search query is specific to a version of a product installed on or associated with the computer system requesting the search. Upon receipt of the search query, a search system accesses a persistent descriptor corresponding to a detected version of the product. The persistent descriptor may be a cookie file stored on the requesting computer system. A product detection module interrogates the computer system to identify the associated products, including the particular versions of those products. The search of a repository of general content related to the product is scoped using the persistent descriptor as a search filter in order to provide version-specific content.
