TSV String, Filter by Date

// GraalJS Script (engine type: 2)
// (c) 2021, Questetra, Inc. (the MIT License)
// Notes:
// Supported date format is "YYYY-MM-DD".
// For "AND search", try to place this Automated Step serially.
// Equals at range boundary values are included in the filter range.
//  (No Problem "2019-10-05<2019-10-05")
//
// Notes(ja):
// 対応する日付フォーマットは "YYYY-MM-DD" です
// "AND検索" は自動工程の直列配置をお試しください
// 範囲境界値におけるイコールはフィルタ範囲に含まれます
// （問題のないフィルタ例 "2019-10-05<2019-10-05"）
