I’m using Grok to check fast-moving topics, and broad web results can mix current reporting with older pages that happen to rank well. For some questions, I only want results from a couple of trusted sites or pages published within a particular date range.

Is there a reliable way to give Grok those search constraints, either in the prompt or through a built-in setting? I’d also like to know whether it makes the limits clear when it cannot find enough matching pages.
