我正在运行Apache pig脚本，我希望能够在字段中查找完整的单词串。例如，我想查找“以下更新已下载并准备安装”
我遇到的问题是matches与RegEx似乎只允许我输入单个词来搜索。所以我最终寻找“跟随”＆amp; “更新”＆amp; “已下载”＆amp; “准备好了”＆amp; “装置”，它们相隔多远并不重要。我只是试图包含更多的单词来试图锁定我正在寻找的东西，但我想看看是否有可能找到整串连续的单词。
以下是我当前过滤器的示例。
downloadFilter = FILTER windowsLog BY ($16 matches '^(?=.*?(following))(?=.*?(updates))(?=.*?(downloaded))(?=.*?(ready))(?=.*?(installation)).*$');
示例记录我正试图点击。
