I find that for some queries, that the Kagi results are quite outdated. It appears that good matches on titles and content can override outdated results. It'd be nice to be able to configure this.
Here is one such example:
I imagine this being an option in the 'Personalised Results' tab. Perhaps presented as a slider to signal a preference for more recent or more 'accurate' results.
It's also something that might be configurable by domain. Discussion forum content doesn't often age all that well for example, at least for technical topics.
