MongoDB:在文档字段中执行文本搜索(使用高级API) [英] MongoDB: Perform a text-search in a document field (using high-level API)

问题描述

可能与此问题有关 使用OPA MongoDB高级API的基本GROUP BY语句.

我希望能够检索名称"字段值包含给定字符串的文档列表.

I want to be able to retrieve a list of documents which "name" field value contains a given string.

这是我的文件清单:

{name: "Charles-Hugo"}, {name: "Jean Pierre"}, {name: "Pierre Dupont"},

{name: "Charles-Hugo"}, {name: "Jean Pierre"}, {name: "Pierre Dupont"},

我希望只能检索名称包含"Pierre"字符串的文档:Jean Pierre和Pierre Dupont.

I want to be able to only retrieve documents which name contains the "Pierre" string: Jean Pierre, and Pierre Dupont.

我知道MongoDB高级API不可能做到这一点. 我已经研究了低级API函数，但是我不知道以安全的Opa类型检索文档的最简单方法是什么.

I know this isn't possible with the MongoDB high-level API. I've looked in the low-level API functions but I don't know what's the easiest way to retrieve my documents in safe Opa type.

我还要在查询中添加跳过/限制选项.

Also I'd like to add skip/limit options to my query.

有什么主意吗?

推荐答案

Opa中的DbGen自动化机制对此提供了支持:

The DbGen automation mechanism in Opa has support for this:

DbSet.iterator(/path/data[name =~ pattern])
