This project adds autosuggest and spell-check for queries in Yioop , a PHP- based search engine. These features help a user by reducing typing, by catching any spelling errors, and by making it easier to repeat searches. Commercial search engines like Google, run on machine clusters and use lists of popular queries from their logs to provide relevant suggestions to users. Efficient storage of data on multiple servers is responsible for minimizing response times. Yioop typically runs on a smaller number of machines compared to commercial search engines. This project aims to implement these computationally intensive functionalities in this constrained environment. This is achieved by performing any needed processing on the client-side without sending queries to the Yioop server.
