NAME

Lucy::Analysis::StandardTokenizer - Split a string into tokens.

SYNOPSIS

my $tokenizer = Lucy::Analysis::StandardTokenizer->new;

# Then... once you have a tokenizer, put it into a PolyAnalyzer:
my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
    analyzers => [ $tokenizer, $normalizer, $stemmer ], );

DESCRIPTION

Generically, “tokenizing” is a process of breaking up a string into an array of “tokens”. For instance, the string “three blind mice” might be tokenized into “three”, “blind”, “mice”.

Lucy::Analysis::StandardTokenizer breaks up the text at the word boundaries defined in Unicode Standard Annex #29. It then returns those words that contain alphabetic or numeric characters.
