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*": </str><str name="querystring">nascar AND author:serg*</str> <str name="parsedquery">(+(+DisjunctionMaxQuery((text:nascar | title:nascar)~0.01) +author:serg*))/no_coord</str> <str name="parsedquery_toString">+(+(text:nascar | title:nascar)~0.01 +author:serg*)</str><lst name="explain"><str name="com.bostonherald/news/international/europe/view/20120409russia_allows_anti-putin_demonstration_in_red_square"> 8.235954 = (MATCH) sum of: 8.10929 = (MATCH) max plus 0.01 times others of: 8.031613 = (MATCH) weight(text:nascar in 0) [DefaultSimilarity], result of: 8.031613 = score(doc=0,freq=2.0 = termFreq=2.0 ), product of: 0.84814763 = queryWeight, product of: 6.6960144 = idf(docFreq=27, maxDocs=8335) 0.12666455 = queryNorm 9.469594 = fieldWeight in 0, product of: 1.4142135 = tf(freq=2.0), with freq of: 2.0 = termFreq=2.0 6.6960144 = idf(docFreq=27, maxDocs=8335) 1.0 = fieldNorm(doc=0) 7.7676363 = (MATCH) weight(title:nascar in 0) [DefaultSimilarity], result of: 7.7676363 = score(doc=0,freq=1.0 = termFreq=1.0 ), product of: 0.9919093 = queryWeight, product of: 7.830994 = idf(docFreq=8, maxDocs=8335) 0.12666455 = queryNorm 7.830994 = fieldWeight in 0, product of: 1.0 = tf(freq=1.0), with freq of: 1.0 = termFreq=1.0 7.830994 = idf(docFreq=8, maxDocs=8335) 1.0 = fieldNorm(doc=0) 0.12666455 = (MATCH) ConstantScore(author:serg*), product of: 1.0 = boost 0.12666455 = queryNorm </str></lst> And here for "nascar +author:serg*": <str name="querystring">nascar +author:serg*</str> <str name="parsedquery">(+(DisjunctionMaxQuery((text:nascar | title:nascar)~0.01) +author:serg*))/no_coord</str> <str name="parsedquery_toString">+((text:nascar | title:nascar)~0.01 +author:serg*)</str><lst name="explain"><str name="com.bostonherald/news/international/europe/view/20120409russia_allows_anti-putin_demonstration_in_red_square"> 8.235954 = (MATCH) sum of: 8.10929 = (MATCH) max plus 0.01 times others of: 8.031613 = (MATCH) weight(text:nascar in 0) [DefaultSimilarity], result of: 8.031613 = score(doc=0,freq=2.0 = termFreq=2.0 ), product of: 0.84814763 = queryWeight, product of: 6.6960144 = idf(docFreq=27, maxDocs=8335) 0.12666455 = queryNorm 9.469594 = fieldWeight in 0, product of: 1.4142135 = tf(freq=2.0), with freq of: 2.0 = termFreq=2.0 6.6960144 = idf(docFreq=27, maxDocs=8335) 1.0 = fieldNorm(doc=0) 7.7676363 = (MATCH) weight(title:nascar in 0) [DefaultSimilarity], result of: 7.7676363 = score(doc=0,freq=1.0 = termFreq=1.0 ), product of: 0.9919093 = queryWeight, product of: 7.830994 = idf(docFreq=8, maxDocs=8335) 0.12666455 = queryNorm 7.830994 = fieldWeight in 0, product of: 1.0 = tf(freq=1.0), with freq of: 1.0 = termFreq=1.0 7.830994 = idf(docFreq=8, maxDocs=8335) 1.0 = fieldNorm(doc=0) 0.12666455 = (MATCH) ConstantScore(author:serg*), product of: 1.0 = boost 0.12666455 = queryNorm </str> <str name="mx.com.elsiglodetorreon/noticia/727525.sacerdotas.html"> 0.063332275 = (MATCH) product of: 0.12666455 = (MATCH) sum of: 0.12666455 = (MATCH) ConstantScore(author:serg*), product of: 1.0 = boost 0.12666455 = queryNorm 0.5 = coord(1/2) </str> You can see, that for first doc in "nascar +author:serg*" all query-params match, but in the second doc only "ConstantScore(author:serg*)".
