How do I search for an entry in tinydb with the the query in json format?

Question

I have a tinydb with entries of the form:

{
    "key0":"value0",
    "key1":"value1",
    "key2":"value2",
    "key3":"value3"
}

and I have a function that sends me:

{
    search:{
        "key0":"value0",
        "key1":"value1"
    },
    update:{
        "key3":"value3.1"
    }
}

the normal search function needs either a Query() or a where('field') with no direct way of passing multiple search queries than hard concatenating them with & operators. is there a way where I can search the db for

{
    "key0":"value0",
    "key1":"value1"
}

and the update the entry with

{
    "key3":"value3.1"
}
