I assume you are referring to the Hibernate Search query DSL. Something like this:

Query luceneQuery = queryBuilder
    .keyword()
      .wildcard()
    .onField("foo")
    .matching("bar*")
    .createQuery();

This DSL is indeed not part Search 3.1.1 and was added later. In this version you need to build your queries by using native Lucene queries. Really all the Search DSL does is under the hood building these native queries for you. In your case you want to look at org.apache.lucene.search.WildcardQuery or you could use the org.apache.lucene.queryParser.QueryParser to use the Lucene query syntax which also allows wildcards.
