I just gave Neeva a shot and it's really great. I love that I can up and down rank domains, and it doesn't appear to filter domains using some shadowy ideological algorithm. I don't seem to have access to that Onebox feature yet but I imagine it's being rolled out by region.

One question: why are there no dates under results? Even for articles where the date is near the top. This is something I rely on heavily to filter out the older results. To provide an example, I searched for "keychron k2v2" and found this article from Sep 26, 2020 (https://appleinsider.com/articles/20/09/26/review-the-keychr...). I then filtered to show me only results from the last year, and this result still popped up. This suggests the Neeva engine doesn't detect dates at all.
