Abstract
Embodiments of a search stemming module at a computer configured to receive a query and identify stems from the query and configured to search a secondary index for variants corresponding to the stems are disclosed. The secondary index may comprise one or more lists of stems associated with variants from a primary index; a search reconfiguration module configured to reformat the query to include variants found from the secondary index; and a search engine configured to implement a search of the primary index using the variants received from the search reconfiguration module.
