I know that wildquery has some performance hit but I need to use it for one of the usecase

Following code does not return any result but changing the search term to exact match returning the results

org.apache.lucene.search.Query query = qb.keyword()
.wildcard()
.onField("firstName")
.matching("queryString" + "*")
.createQuery();


I have tried with followig input string

Query String------> Results
1. San* ---> No Result
2. Santosh ----> 5 Results

Is there anything missing in my code. Following links talks about the wild card query
http://docs.jboss.org/hibernate/search/3.3/reference/en-US/html/search-query.html
refer the secion - 5.1.2.3. Wildcard queries

Found It :)

fullTextSession.createFullTextQuery(new WildcardQuery(new Term("firstName", queryString + "*")), User.class);
