B<EPrints::Index::Tokenizer> - text indexing utility methods
=head1 DESCRIPTION
This module provides utility methods for processing free text into indexable things.
=head1 METHODS
=over 4
=cut
package EPrints::Index::Tokenizer;
######################################################################
=pod
=item @words = EPrints::Index::Tokenizer::split_words( $session, $utext )
Splits a utf8 string into individual words.
=cut
######################################################################
sub split_words
{
my( $session, $utext ) = @_;
if( ref($utext) eq "Unicode::String" )
{

}
# fix malformed UTF-8 data
$utext = Encode::decode("UTF-8", $utext, Encode::FB_DEFAULT);
return split /[^\w']+/, $utext;
}
=item @terms = EPrints::Index::Tokenizer::split_search_value( $session, $value )
Splits and returns $value into search terms.
=cut
sub split_search_value
{
my( $session, $value ) = @_;
# transliterate to English
$value = apply_mapping( $session, $value );
return split /[^\w'\*]+/, $value;
}
######################################################################
=pod
=item $utext2 = EPrints::Index::Tokenizer::apply_mapping( $session, $utext )
Replaces certain unicode characters with ASCII equivalents and returns
the new string.
This is used before indexing words so that things like umlauts will
be ignored when searching.
=cut
######################################################################

} split(//, $utext));

##############################################################################
# Mappings and character tables
##############################################################################
# This map is used to convert Unicode characters
# to ASCII characters below 127, in the word index.
# This means that the word Fête is indexed as 'fete' and
# "fete" or "fête" will match it.
# There's no reason mappings have to be a single character.
