Always when I open the sentence-search dialog (Dashboard, looking-glass icon), before I can start searching, the system performs a default search which I find completely useless: it adds an unnecessary delay (sometimes quite long), and I have no use for the search result whatsoever.
Also, the input field for the query does not automatically have input focus, and can only be set manually after the default search is finished.
I fully agree that the "Search of Randomness" is totally unnecessary (… and unnecessary means excess energy consumed, which means excess carbon footprint).
N.B. I don’t recall seeing the “Loading…” take more than a fraction of a second on my PC - I certainly wouldn’t have enough time to take a screenshot - but there are many reasons why that might be the case, and I don’t mean that in any way to detract from your bug report.
