I tested it.
With default "qf=title text" in solrconfig and "mm=100%"
i get the same result(1) for "nascar AND author:serg*" and "+nascar
+author:serg*", great.
With "nascar +author:serg*" i get 3500 matches, in this case the
mm-parameter seems not to work.
Here are my debug params for "nascar AND author:serg*":

You can see, that for first doc in "nascar +author:serg*" all
query-params match, but in the second doc only
"ConstantScore(author:serg*)".
But with an "mm=100%" all query-params should match.
