### Question:
QueryBuilders { static RangeQueryBuilder rangeQuery( String name ) { return new RangeQueryBuilder( name ); } private  QueryBuilders();   }### Answer:
@Test public void range() throws Exception { assertEquals( "{\"range\":{\"f\":{\"lt\":0}}}", toJson( QueryBuilders.rangeQuery( "f" ).lt( 0 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gt\":0}}}", toJson( QueryBuilders.rangeQuery( "f" ).gt( 0 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gte\":0}}}", toJson( QueryBuilders.rangeQuery( "f" ).gte( 0 ) ) ); assertEquals( "{\"range\":{\"f\":{\"lte\":0}}}", toJson( QueryBuilders.rangeQuery( "f" ).lte( 0 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gt\":1,\"lt\":2}}}", toJson( QueryBuilders.rangeQuery( "f" ).gt( 1 ).lt( 2 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gt\":11,\"lt\":0}}}", toJson( QueryBuilders.rangeQuery( "f" ).lt( 0 ).gt( 11 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gt\":1,\"lte\":2}}}", toJson( QueryBuilders.rangeQuery( "f" ).gt( 1 ).lte( 2 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gte\":1,\"lte\":\"zz\"}}}", toJson( QueryBuilders.rangeQuery( "f" ).gte( 1 ).lte( "zz" ) ) ); assertEquals( "{\"range\":{\"f\":{\"gte\":1}}}", toJson( QueryBuilders.rangeQuery( "f" ).gte( 1 ) ) ); assertEquals( "{\"range\":{\"f\":{\"gte\":\"zz\"}}}", toJson( QueryBuilders.rangeQuery( "f" ).gte( "zz" ) ) ); assertEquals( "{\"range\":{\"f\":{\"gt\":\"a\",\"lt\":\"z\"}}}", toJson( QueryBuilders.rangeQuery( "f" ).gt( "a" ).lt( "z" ) ) ); assertEquals( "{\"range\":{\"f\":{\"gte\":3}}}", toJson( QueryBuilders.rangeQuery( "f" ).gt( 1 ).gt( 2 ).gte( 3 ) ) ); assertEquals( "{\"range\":{\"f\":{\"lte\":3}}}", toJson( QueryBuilders.rangeQuery( "f" ).lt( 1 ).lt( 2 ).lte( 3 ) ) ); }
