.IP "stem({ \-words => \e@words, \-locale => 'de', \-exceptions => \e%exceptions });" 4
.IX Item "stem({ -words => @words, -locale => 'de', -exceptions => %exceptions });"
Stems a list of passed words using the rules of German Returns
an anonymous array reference to the stemmed words.
.Sp
Example:
.Sp
.Vb 4
\&  my $stemmed_words = Lingua::Stem::De::stem({ \-words => \e@words,
\&                                              \-locale => \*(Aqde\*(Aq,
\&                                          \-exceptions => \e%exceptions,
\&                          });
.Ve
.IP "stem_caching({ \-level => 0|1|2 });" 4
.IX Item "stem_caching({ -level => 0|1|2 });"
Sets the level of stem caching.
.Sp
\&'0' means 'no caching'. This is the default level.
.Sp
\&'1' means 'cache per run'. This caches stemming results during a single
    call to 'stem'.
.Sp
\&'2' means 'cache indefinitely'. This caches stemming results until
    either the process exits or the 'clear_stem_cache' method is called.
.IP clear_stem_cache; 4
.IX Item "clear_stem_cache;"
Clears the cache of stemmed words
