A snippt codes

from tinydb import TinyDB, Query
db =  TinyDB("test.json")
db.insert({"id": 1})

q = Query()
records = db.search(q.id == 1)
records[0]["name"] = "N1"

db.search(q.id==1)
>>[{'id': 1, 'name': 'N1'}]
db.all()
>>[{'id': 1}]

You can see that modifications to the search function result affect the later search results. But it doesn't change the records on the disk. Is it expected or not?

We need to remove the cache read until we find a solution. Reading from db is ok than wrong data read from cache after modified.
