How can you implement the "Did you mean: " like Google does in some search queries ? PS: I am using sphinx in my product. Can you suggest how can I implement this. Any guides or suggestions for some other search engines who has this functionality are most welcomed. I am using rails2.3.8, if that helps One Solution can be: Make a dictionary of known "keywords" or "phrases", and in search action if nothing is found then run a secondary query in that dictionary. Update that dictionary whenever a searchable entry is created say, a blog post or username. query = "supreman" dictionary = ["superman", "batman", "hanuman" ...] (in DB table) search(query) if no results, then search in dictionary (where "keyword" LIKE query or "phrase" LIKE query) => "superman" Check in sphinx or solr documentation. They might have a better implementation of this "Like" query which returns a % match. display -> Did you mean "superman"? But the point is how to make it efficient?
