10 my $stems = Lingua::Stem::De::stem({ -words => $word_list_reference,
11 -locale => 'de',
12 -exceptions => $exceptions_hash,
13 });
14
16 This routine applies a stemming slgorithm to a passed anon array of
17 German words, returning the stemmed words as an anon array.
18
19 It is a 'convienence' wrapper for 'Text::German' that provides a
20 standardized interface and caching.

32 stem({ -words => \@words, -locale => 'de', -exceptions => \%exceptions
33 });
34 Stems a list of passed words using the rules of German Returns an
35 anonymous array reference to the stemmed words.
36
37 Example:
38
39 my $stemmed_words = Lingua::Stem::De::stem({ -words => \@words,
40 -locale => 'de',
41 -exceptions => \%exceptions,
42 });
43
44 stem_caching({ -level => 0|1|2 });
45 Sets the level of stem caching.
46
47 '0' means 'no caching'. This is the default level.
48
49 '1' means 'cache per run'. This caches stemming results during a
50 single
51 call to 'stem'.
52
53 '2' means 'cache indefinitely'. This caches stemming results until
54 either the process exits or the 'clear_stem_cache' method is
55 called.
56
57 clear_stem_cache;
58 Clears the cache of stemmed words
