Lucene(3.5)のいくつかのクエリー

いくつかのクエリの使用方法は次のコードです.
内
数値範囲クエリー:索引時のフィールドは次のように保存されます.
new NumericField(name,  Field.Store.YES(NO), true(false).setIntValue( num );
Query numericRangeQuery = NumericRangeQuery.newIntRange("size", 20, 150, true, true);
時間範囲クエリーとは、Dateがlong型変数に基づいて構築されたことを知っているため、数値範囲クエリーです.
だから使い方は同じですが、入力した日付フォーマットをlongに変換する必要があります.
