This is a fairly frequently requested and missing feature in Lucene/Solr...
Lucene actually "knows" this information while it's scoring each document; it's just that it in no way tries to record that. If you will only do this on a few documents (eg the one page of results) then piggybacking on the highlighter is an OK approach. If you need it on more docs than that, then probably you should customize how your queries are scored to also tally up which docs had which terms.
