elasticsearch - ElasticSearch Search-as-you-type field type field with partial search

Question

我最近更新了我的 ngram 实现设置以使用 Search-as-you-type 字段类型。 https://www.elastic.co/guide/en/elasticsearch/reference/7.x/search-as-you-type.html

这很好用，但我注意到部分搜索不起作用。如果我搜索数字 00060434，我会得到想要的结果，但我也希望能够搜索 60434，那么它应该返回文档 3。

有没有办法使用Search-as-you-type 字段类型来做到这一点，或者我只能用 ngrams 做到这一点？
