Google’s Gary Illyes announced that they are going to release a separate mobile search index within months. At present, Google has a single index of documents for search. With the launch of separate search index, it will become the main index that the search engine uses to respond to queries.
Gary first announced that they were working with the idea of a mobile index last year at SMX East.
But, Google has not clarified that how the mobile index will work. Since the mobile index is the primary index, they are yet to confirm whether it contains only mobile friendly content or can be used for desktop enquiries as well.
