Describe the bug
The error msg does not show the complete usage for query without all the required parameters: when run
milvus_client.query(collection_name)
it shows "<MilvusException: (code=65535, message=empty expression should be used with limit)"
Expected Behavior
sth like "ids or filter or limit cannot be empty"
please specify the param "filter" or the param "limit"
Steps/Code To Reproduce behavior
import time
import numpy as np
from pymilvus import (
MilvusClient,
)
dim = 8
collection_name = "hello_milvus"
milvus_client = MilvusClient()
has_collection = milvus_client.has_collection(collection_name, timeout=5)
if has_collection:
milvus_client.drop_collection(collection_name)
milvus_client.create_collection(collection_name, dim, consistency_level="Strong", metric_type="L2")
print(fmt.format(" all collections "))
print(milvus_client.list_collections())
print(fmt.format(f"schema of collection {collection_name}"))
print(milvus_client.describe_collection(collection_name))
rng = np.random.default_rng(seed=19530)
rows = [
{"id": 1, "vector": rng.random((1, dim))[0], "a": 100},
{"id": 2, "vector": rng.random((1, dim))[0], "b": 200},
{"id": 3, "vector": rng.random((1, dim))[0], "c": 300},
{"id": 4, "vector": rng.random((1, dim))[0], "d": 400},
{"id": 5, "vector": rng.random((1, dim))[0], "e": 500},
{"id": 6, "vector": rng.random((1, dim))[0], "f": 600},
]
print(fmt.format("Start inserting entities"))
insert_result = milvus_client.insert(collection_name, rows, progress_bar=True)
print(fmt.format("Inserting entities done"))
print(insert_result)
milvus_client.query(collection_name)

In fact, we consider that not specifying any parameters implies a constant value of True. In this case, it is necessary to specify the limit.
