Is stemming or the use of wildcards allowed?

The Google Mini searches for exactly the words that you enter into the search box. However, customers can create a list of synonyms for specific keywords using the Admin Console so that a search for one term would also suggest additional terms. Synonyms are displayed as additional suggested searches on the search results page. You may want to consider the Google Search Apppliance if this is an important business consideration. Experience enhanced search relevance with context sensitive stemming and automated synonyming. Context matters, and only Google has data from billions of queries to train the system.
