This session aims to explain the implementation and use case for spellchecking in Trovit search engine. Trovit is a classified ads search engine supporting several different sites, one for each on country and vertical. Our search engine supports multiple indexes in multiple languages, each with several millions of indexed ads. Those indexes are segmented in several different sites depending on the type of ads (homes, cars, rentals, products, jobs and deals). We have developed a multi-language spellchecking system using solr and lucene in order to help our users to better find the desired ads and avoid the dreaded 0 results as much as possible. As such our goal is not pure orthographic correction, but also suggestion of correct searches for a certain site.
