Question

I am executing query using WildcardQuery of Lucene.but I don’t know why the result cannot be found.
Below are the details.

Here is the code for create WildcardQuery,and The record of Field Name :’Full Name’ Value:’ABC123DD456CC’ is existed Index Document.

BooleanQuery booleanQuery = new BooleanQuery();
for (IndexQueryField field : quickSearchFields)
{
    Query query = new WildcardQuery(new Term(queryField.getFieldName(),"ABC*DD*CC"));
    booleanQuery.add(query, BooleanClause.Occur.SHOULD);
}

The part of code: Executing query:

Session hibernateSession               = (Session) em.getDelegate();
FullTextSession session                = SwitchSession.getFullTextSession(hibernateSession, specifyIndexName);

// Set Hibernate flushMode
session.setFlushMode(FlushMode.MANUAL);
// Ignore Hibernate Cache
session.setCacheMode(CacheMode.IGNORE);

            FullTextQuery query = session.createFullTextQuery(booleanQuery,XXX.class);
List list = query.setFirstResult(1).setMaxResults(100).list();

The list is empty, i am sure the ‘ABC123DD456CC’ is existed in Lucene Document.
I just want to do it with WildcardQuery. Any help will be thankful!

I believe that last line should be:

List list = query.setFirstResult(0).setMaxResults(100).list();

Since results are numbered from 0. If there is only 1 document matching that search, which seems likely enough, that probably explains why you’re getting nothing (having skipped the first and only result, at index 0).
