When doing a request with all parameters left as default, you will notice the “Text” field of the related topics will often miss a space. If you make a request with “ULB”, you will get this:

With “Washington”:

“Text”: “George WashingtonThe first President of the United States, the Commander-in-Chief of the Continental Army during…”

etc.

My impression is that the title and the text are merged.
