文本索引不根据语言返回结果

Question

我创建了一个收藏链接。 每个文档都有一种现场语言。 当我尝试搜索时，无法根据语言进行全文搜索。

我尝试使用“it”/“en”和“italian/english”（https://docs.mongodb.com/manual/reference/text-search-languages/#text-search-languages） 我尝试使用 language_override (https://docs.mongodb.com/manual/tutorial/specify-language-for-text-index/#create-a-text-index-for-a-collection-in-multiple-languages)

use search

//Insert some data
db.links.insert({"language": "it", "content": "quando cammino ho male al ginocchio"})
db.links.insert({"language": "it", "content": "ho male alle ginocchia"})
db.links.insert({"language": "en", "content": "A lot of pain knee"})

//Create index
db.links.createIndex({content: "text"})

//Test search but with empty result
db.search.find({$text: {$search: "ginocchia"}})
//I try default english works
db.links.find({$text: {$search: "knee"}})

//So I drop indexes and try language_override
db.links.dropIndexes()
db.search.createIndex({content: "text"}, {language_override: "language"})

//Test search but with empty result
db.search.find({$text: {$search: "ginocchia"}})
//I try default english works
db.links.find({$text: {$search: "knee"}})

//If I set default_language in "it" working in italian and not in english.

我想如果我插入“ginocchia”会得到第一个文件，如果我插入“knee”会得到最后一个。

我在 find 中也使用了 $language，现在它可以工作了
