当我匹配"2019.*"时可以匹配到以2019开头的所有数据
elasticsearch 中被正则的字段为keyword，具体如下
regexpQuery("last_update_string_time", "2019*")));elasticsearch 中被正则的字段为keyword，具体如下
"last_update_string_time": "2019-03-26 18:51:05"

The regexp query allows you to use regular expression term queries. See Regular expression syntax for details of the supported regular expression language. The "term queries" in that first sentence means that Elasticsearch will apply the regexp to the terms produced by the tokenizer for that field, and not to the original text of the field.
