Abstract
A search query that includes a first spelling of a term is received. A second spelling of the term is generated. A first set of items that are associated with the first spelling of the term is accessed, and a second set of items that are associated with the second spelling of the term is accessed. A comparison is performed between the first set to the second set. A determination is made as to how to respond to the search query based, at least in part, on the comparison. The response may include a suggested search query that includes the second spelling of the term. The second spelling may be a suggested spelling correction or an alternative spelling. The response may include search results that are relevant to a search query that includes the first spelling of the term, the second spelling, or both the first and second spelling.
