how to decode Redis ft search query?
问题
以下是代码的翻译部分：
我是新手学习 Redis，尽力学习一切可能的知识，以后想将其用于我的网站缓存。但是，我目前遇到了一个小问题，我不知道如何解码来自 ft 函数的返回查询。
以下是代码：
import redis
import json
from redis.commands.json.path import Path
from redis.commands.search.query import Query, NumericFilter
r = redis.Redis(host="192.168.196.75", port=6379)
user1 = {
"name": "Paul John",
"email": "paul.john@example.com",
"age": 42,
"city": "London",
"id": 1,
"username": "Paul Walker",
}
loc = r.ft("Idx").search(query="@username:Paul")
print(loc)
输出结果是 Result{1 total, docs: [Document {'id': 'user:1', 'payload': None, 'json': '{"name":"Paul John","email":"paul.john@example.com","age":42,"city":"London","id":1,"username":"Paul Walker"}'}]}
正如您所看到的，一切都运行正常，但我无法提取包含信息的字典，我可以尝试进行多个步骤，比如拆分和切片，但我认为有一个函数可以做到这一点，但我找不到它。如果有人知道是什么函数，那将非常有帮助。感谢阅读我的问题。

So I am new to redis and I am trying to learn everything I possible can and later want to add this for caching in my website.
But, I am currently encountering a very small problem, I have no idea of any function how to decode the return query from the ft function.
The code is below:
import redis
import json
from redis.commands.json.path import Path
from redis.commands.search.query import Query,NumericFilter
r=redis.Redis(host="192.168.196.75",port=6379)
user1 = {
"name": "Paul John",
"email": "paul.john@example.com",
"age": 42,
"city": "London",
"id":1,
"username":"Paul Walker",
}
# r.json().set("user:1",Path.root_path(),user1)
loc=r.ft("Idx").search(query="@username:Paul")
print(loc)
The output I am getting is Result{1 total, docs: [Document {'id': 'user:1', 'payload': None, 'json': '{"name":"Paul John","email":"paul.john@example.com","age":42,"city":"London","id":1,"username":"Paul Walker"}'}]}
As you can see everything is working fine, But I am not able to derive the dictioniary that has the information, I can try to make many steps like splitting and slicing but I think there is a function for this which I am not able to find.
It would be very helpful If anyone knows what that is. Thank you for reading my question

只获取文档，您可以使用.docs，例如：
loc=r.ft("Idx").search(query="@username:Paul").docs 以检索所有结果，或者使用.docs[0] 检索第一个元素。
英文:
for retrieving just the documents you can use the .docs such as:
loc=r.ft("Idx").search(query="@username:Paul").docs retrieving all results or .docs[0] for the first element and on
