++Stemming\r
++--------\r
++\r
++**Stemming** in notmuch means is that these searches\r
++\r
++::\r
++\r
++        notmuch search detailed\r
++        notmuch search details\r
++        notmuch search detail\r
++\r
++will all return identical results, because Xapian first "reduces" the\r
++term to the common stem (here 'detail') and then performs the search.\r
++\r
++There are two ways to turn this off: a search for a capitalized word\r
++will be performed unstemmed, so that one can search for "John" and not\r
++get results for "Johnson"; phrase searches are also unstemmed (see\r
++below for details).  Stemming is currently only supported for\r
++English. Words in other languages will be performed unstemmed unless\r
++somebody teaches Xapian how to perform stemming for that language.\r
++\r
++Wildcards\r
++---------\r
++\r
++It is possible to use a trailing '\*' as a wildcard. A search for\r
++'wildc\*' will match 'wildcard', 'wildcat', etc.\r
