I'm working with Firestore in Python and have a data query challenge I'm hoping to get some advice on.

My documents in Firestore are structured as follows:

{
 "key1": "value1",
 "key2": {
 "subKey1": [
 {
 "arrayKey1": "arrayValue1",
 "arrayKey2": "arrayValue2"
 },
 {
 "arrayKey3": "arrayValue3",
 "arrayKey4": "arrayValue4"
 }
 ],
 "subKey2": "subValue2"
 }
}

My goal is to query documents where the value of arrayKey1 within the subKey1 array matches a specific value (for example, target_arrayValue1), regardless of the arrayKey2 in the same dictionary.

Here's an example of what my query currently looks like:

docs = query.where(
 filter=FieldFilter(
 "key2.subKey1",
 "array_contains",
 {
 "arrayKey1": "target_arrayValue1",
 "arrayKey2": "arrayValue2"
 }
 )
).stream()

This approach, however, requires a full match of the dictionary, which is not ideal.

Describe the solution you'd like
My "ideal" code would do something like this:

docs = query.where(
 filter=FieldFilter(
 "key2.subKey1.0.arrayKey1", 
 "==",
 "target_arrayValue1"
 )
).stream()

Is there an appropriate way to structure my query to achieve this? Any insights or examples would be greatly appreciated! Thanks in advance.
