for collection in collections:
print(collection)
# Find a specific document in the Wikipedia collection.
collection = cognica.find_collection("Wikipedia")
df = collection.find({
"page_id": 42
}, to_pandas=True)
print(df)
Next Version (Work in progress)

print(workspace)
# Open the workspace and list the collections.
workspace = ws.find_workspace("test")
