marc-search.cgi "find all" problem

Does anyone have a fix to a problem which has long plagued me, namely,
that when one searches one's mail archives with marc-search.cgi, using the
"find all of these words" (boolean AND) option, one is only returned
messages which match all the words ON A SINGLE LINE.  This is extremely
misleading and furthermore, not what the help says should happen.  Thanks
very much.
