Ok ! According to your requirements , it is a very simple scenario. The *FSTLookup* approach should do the trick for you! Take a look to the official documentation to see the parameter supported [1] ( it is in Solr but it gives to you the idea of the parameter required) . This section of my blog should help as well (it is for Solr but Solr uses the underlying Lucene core to provide the suggestions)[2]
