"must_not" doesn't work?

[wkt]

Code:
from milvus import Milvus, DataType

collection_name = 'test'
client = Milvus(host='127.0.0.1', port='19530')

collection_param = {
"fields": [
{"name": "c0", "type": DataType.INT64},
{"name": "c1", "type": DataType.INT64},
{"name": "vec", "type": DataType.FLOAT_VECTOR, "params": {"dim": 2}}
],
"auto_id": True
}
ivf_param = {"index_type": "FLAT", "metric_type": "L2", "params": {"nlist": 2048}}

client.drop_collection(collection_name)
client.create_collection(collection_name, collection_param)
client.create_index(collection_name, "vec", ivf_param)

c0_list = [1, 2, 3, 4, 5, 6]
c1_list = [3, 4, 5, 6, 7, 8]
vec_list = [[0., 0.1], [0., 0.2], [0., 0.3], [0., 0.4], [0., 0.5], [0., 0.6]]

entities = [
{"name": "c0", "values": c0_list, "type": DataType.INT64},
{"name": "c1", "values": c1_list, "type": DataType.INT64},
{"name": "vec", "values": vec_list, "type": DataType.FLOAT_VECTOR}
]

eids = client.insert(collection_name, entities)
client.flush()
ens = client.get_entity_by_id(collection_name, ids=[eids[0]], fields=['vec'])

vecs = [[0., 0.02], [0., 0.35]]
dsl = {

"bool": {
    "must": [
        {
            "vector": {
                "vec": {
                    "topk": 3,
                    "metric_type": "L2",
                    "query": vecs,
                    "params": {
                        "nprobe": 10
                    }
                }
            },
        }
    ],
},
"must_not": [
    {
        "term": {
            "c0": [1, 2],
            "c1": [3, 6]
        }
    }
]

}

res = client.search(collection_name, dsl, fields=['c0', 'c1', 'vec'])
for y in res:
for x in y:
print(x.entity.get('c0'), x.entity.get('c1'), x.entity.get('vec'), "\n")

结果：

Data of c0 == 1,c0 == 2 and c1 == 6 were not filtered out.

In 0.11.0, we only recommend you to use must in your dsl. Because there are some bugs in the validation check of 'should' and 'must_not' query, and these bugs will be fixed in 0.11.1.

It milvus-0.10.3 has this bug?

[sahuang]

Milvus 0.10.3 does not support DSL query.

[wkt]

Milvus 0.10.3 does not support DSL query.

OK,when 0.11.1 will be release ?

[sahuang]

There isn't a precise timeline but it will be released after all bugs are cleared.
