rest - What is the correct HTTP status code for search results not found?

Question

We are implementing REST APIs in Java.

For GET REST endpoint, if I search for something:

1. If any records/record found, then it will return 200 status code and results/result.

2. If NO records found, what is the correct HTTP status code ?

When I searched in Google and SO, I found different answers like:

200 with empty list (if the API response is item but NOT list, then I can't send empty list)
204 No Content
404 Not Found

what is the correct HTTP status code if record not found or search results not found ?

有两种不同的场景：

• 要检索没有项目的资源集合（例如）的表示形式，请返回一个空数组。GET /products?name=foo200

• 要检索不存在的单个资源（例如）的表示，请返回。GET /products/1404

例如204，状态码用于作为PUT操作的结果，允许服务器指示该操作已成功应用于目标资源。它不适合上述场景。
