I get inconsistent search results based on whether I use capital letters or lowercase letters on my search terms. I shouldn't get different results based on the fact that I didn't use capitalisation on a search. I believe that most people search using lowercase. The search term Test vs test shows very different results. "Test" looks great, showing me YouTube videos, 'Blast from the past' etc. While lowercase "test" just shows text-based results.
The side widgets results sometimes appear only when searching in lowercase or uppercase.
I also find that widgets completely malfunction based on having your regional searches set to International, US, Australia, UK etc. The Wikipedia widget results sometimes display, sometimes, don't.
Here's an example of the inconsistency on a search from both results and widgets.
I re-subscribed today on the starter plan to see if these bugs have been fixed, but sadly they are still present.
I find this to be a deal breaker as I need reliable, consistent results.
I expect consistent search results regardless of whether capitalisation is used or not and for widgets to behave consistently between region searches.
