Apache Lucene索引器搜索

Question

我正在使用Apache lucene Indexer Search搜索文本，但是在使用该工具时，我遇到以下问题。

If I indexed word "Steve" and if I want to search that word then If 
I search using following possibilities like *S*, *St* , *Ste*, *Stev* 
then It gives correct result.

But If I search using whole word like *Steve* then Its giving zero hits.

例如我的代码如下。

--------call to Search ------  
TopDocs foundDocs2 = searchByFirstName("*Steve*", searcher);
-------------------------------------------------------------
private static TopDocs searchByFirstName(String firstName, IndexSearcher searcher) throws Exception
{

        MultiFieldQueryParser mqp = new MultiFieldQueryParser(new String[]{"firstName"}, new StandardAnalyzer());
        mqp.setAllowLeadingWildcard(true);
        Query q =mqp.parse(firstName);
        TopDocs hits = searcher.search(q, 10);
        return hits;
}

如果我搜索整个单词，则返回零命中。

我的索引编写器如下。

writer = getIndexWriter();
List<Document> documents = new ArrayList<>();
Document document1 = createDocument(1, "Steve", "Richard", "richard.com");
writer.addDocument(document1);
writer.commit();



 private static Document createDocument(Integer id, String firstName, String lastName, String website)
    {
        Document document = new Document();
        document.add(new StringField("id", id.toString() , Field.Store.YES));
        document.add(new TextField("firstName", firstName , Field.Store.YES));
        document.add(new TextField("lastName", lastName , Field.Store.YES));
        document.add(new TextField("website", website , Field.Store.YES));
        return document;
    }


 private static IndexWriter createWriter() throws IOException
    {
        FSDirectory dir = FSDirectory.open(Paths.get(INDEX_DIR).toFile());
        IndexWriterConfig config = new    IndexWriterConfig(Version.LUCENE_44,new StandardAnalyzer(Version.LUCENE_44));
        IndexWriter writer = new IndexWriter(dir, config);
        return writer;
    }
