You know your specific landscape
You have spent years building — the citations, the colleagues, the subfields and specialisms you navigate. You know who is doing the interesting work. You know where the gaps are.
What is harder to explore is the landscape adjacent to your specialism. Or perhaps how your field intersects with works and topics new to you.
Who is working on the same problem from a different discipline? Who cited your paper and took it somewhere you never expected?
Boolean search is fine for a couple of topics, if done accurately. Integrity is built for intersections, iteration and serendipity.
The map to your next landscape could already be in here.
