Many thanks to Erik and Ollie for responding - a lot of ideas and I'll have my work cut out grokking them properly and thinking about what to do. I'll respond further as that develops.

What happens is they enter some silly query, like searching for all stories with a single common non-stop-word in them, and with the usual sort criterion of by date (ie. a field) descending, and a limit of, say 25. So Lucene then presumably has to haul out a massive resultset, sort it, and return the top 25 (out of 500,000 or whatever). Isn't that how it goes? Or am I missing something horribly obvious.
