I don't think there's any way right now to do this, other than by
customising the source code. There isn't a template variable that tells
you, on a document by document basis, which search words matched that
document. The best you could do right now is just show the whole query
string, either as $(WORDS) which is as entered in the input parameter
"words", or as $(LOGICAL_WORDS) which is the expanded query.
