DirectoryReader dirReader = DirectoryReader.open(indexDirectory); 
indexSearcher = new IndexSearcher(dirReader); 

ScoreDoc[] queryResults = indexSearcher.search(query, numOfResults).scoreDocs; 

List<IndexItem> results = new ArrayList<IndexItem>(); 
for (ScoreDoc scoreDoc : queryResults) { 
    Document doc = indexSearcher.doc(scoreDoc.doc);

Answer 1

有不同类型的分析仪可用，请检查与您的要求不同的分析仪。 Comparison of Lucene Analyzers。这也可能有助于Lucene: Multi-word phrases as search terms

Answer 2

尝试

短语查询：

Query query = parser.parse("\"Labor Law\""); 

所有条件必须存在

Query query = parser.parse("+Labor +Law"); 

您还可以创建查询自己这样

BooleanQuery query= new BooleanQuery(); 
TermQuery clause1 = new TermQuery(new Term("content", "Labor")); 
TermQuery clause2 = new TermQuery(new Term("content", "Law")); 
query.add(new BooleanClause(clause1, BooleanClause.Occur.MUST)); 
query.add(new BooleanClause(clause1, BooleanClause.Occur.MUST));
