Multiline String, Filter by Text

// Notes:
// Cannot specify search terms that contain a comma.
// For "AND search", try to place this Automated Step serially.
// Special characters in search text settings have no meaning (literal string).
// Notes(ja):
// カンマを含む検索語は指定できません
// "AND検索" は自動工程の直列配置をお試しください
// 検索テキスト設定の特殊文字に意味はありません（リテラル文字列）
