SMS-based web search is different from traditional web search in that the final response to a search query is limited to a very small number of bytes typically 1-2 SMS messages, 140 bytes each. SMS-based web search is also a non-interactive search problem where the user has to specify a query and obtain a response in one round of search. Enabling search with such constraints is challenging. Several search engines have developed SMS-based search capabilities in recent years and many of these search engines are limited in their recognized topics phone, address, location, weather etc., involve a human in the loop or apply to only specific types of search queries.
