Hey there!
\nThanks for the great work!
\n
I am currently struggling a bit with the filter_docs:
\n
I have a docsList of a doc like this:
\n
class ImageDoc(BaseDoc):\n    url: ImageUrl\n    test_index: Optional[int]\n    local_path: Optional[str]\n    tensor: Optional[ImageTorchTensor]\n    embedding: Optional[AnyEmbedding]
\n
Now I want to filter out all the docs which have either test_index 3 or 9 . What would be the query for this? This does not work:
\n
query = {\n    '$and': {\n        'test_index' : {'$neq' : 3},\n        'test_index' : {'$neq' : 9}\n    }\n}\n
\n
And only filters out only the 9 (second part of the query). This seems to be always happening when using two times the same index in the query.
\n
What would be the correct approach for this?
\n
Currently I am solving this with a regex expression, but that does not seem right haha
\nThanks!

Hello @simonschoenhofen .
\n
I finally got time to look at this issue.
\n
This does not seem to be a bug, since the query is a dictionary, a dictionary cannot contain 2 entries of the same key and this is why docarray only sees one of the entries.
\n
I would say that the query should be designed differently using the nin (not in a set) clause:
\n
query = {
\n'test_index' : {'$nin' : [3, 9]},
\n}
