When I perform a search for 'Vegas', I get all results including 'Vega'. If I exclude 'Vega' in the search, it also excludes 'Vegas'. Is there a way to search just for 'Vegas'?
We don't have a search option for that because we use "stemming" when indexing our content. (Stemming is the process that basically merges search results for "work", "working", "worked" and "works" to a common root.) I think Google may be able to do what you want.
