最后我有：

[{Title Bonjour Content Bonjour}]{"id":"5DJ0u81WR","title":"Title Bonjour","created_at":"2019-11-14T23:16:26.028333176Z","content":"Content Bonjour"}&{documents _doc 5DJ0u81WR 1 created 0xc0001581c0 2 1 0 false}result&{map[Content-Type:[application/json; charset=UTF-8]] 4 false 0 []  0xc00015b3e0 map[] map[] false   0xc000158600 0}Found a total of 0 docs

我不明白为什么。该文档似乎已创建，但无法通过搜索找到。...

您正在使用术语查询来匹配完全相同的字段

Title Bonjour!=Bonjour

此行

termQuery := elastic.NewTermQuery("title","Bonjour")

等效于

where title='Bonjour'

在mysql中，如果您要匹配但不完全匹配，则可以使用匹配查询

matchQuery := elastic.NewMatchQuery("title","Bonjour")
