Try

Phrase query:

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

All terms must be present

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

You can also create query yourself like this

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));
