I was trying to use the Knowledge API to manipulate the datasets that I created. However, I found that the current Knowledge API does not support retrieval testing of a certain dataset.

2. Describe the feature you'd like to see

Support retrieval testing for a certain dataset in Knowledge API.

This will be beneficial to custom knowledge building, through large amount of retrieval testing with API calling, I could collect and analysis the dataset and get better idea on how to improve the presentation and custom settings of it.

4. Additional context or comments
