You are creating grams only while indexing and not querying hence 'ludlwo' would not match. Your analyzer will create the following grams while indexing for 'ludlow': lu lud ludl ludlo ludlow and hence would not match to 'ludlwo'.
Either you need to create gram while querying also or use Edit Distance.
