Scripted fields in Kibana are powered by lucene expressions, which only support numeric operations right now. Kibana中的脚本字段由lucene表达式提供支持，该表达式目前仅支持数字操作。 Support for things like string manipulation and date parsing will probably be added at some point, but I doubt scripts will even support executing aggregations. 可能会在某些时候添加对字符串操作和日期解析等内容的支持，但我怀疑脚本甚至会支持执行聚合。
Scripted fields are primarily for converting a number before using it, or creating a synthetic field which is the combination of two or more other fields. 脚本字段主要用于在使用数字之前转换数字，或创建合成字段，该字段是两个或更多其他字段的组合。 Down the road they may even support things like extracting the day of the week from a date, or the portion of a string that matches a regular expression. 在路上，他们甚至可以支持诸如从日期中提取星期几或者与正则表达式匹配的字符串部分。
