When I messed with it I used Kagi's search and I didn't have that issue (not claiming they're the best, they're the only one I tried).

They filter their results through their AI, though, so you get a sort of meta-summary of the top few results. It did well with geopolitical news stuff, but I've not tried a hard science sort of query.

Try Parallel.ai (no affiliation). Instead of keywords, the model writes objectives.
