Possibly you would like to give some tolerance in the distance between the terms ( positional queries ~N) Eg: "cardinal healthcare"~2 This depends on your use case really. > q=SellerName:car - nothing returned > q=SellerName:card - all 4 returned > > This is a little bit different, as we enter the autocompletion world, and in a very weird way, why car should not return all the docs ? Only because it's length ? In the case it's easy peasy, you configure your edge ngram token filter with a min Ngram of 4 and maximum of N .
