=head1 NAME

Lucy::Analysis::Token - Unit of text.


        my $token = Lucy::Analysis::Token->new(
            text         => 'blind',
            start_offset => 8,
            end_offset   => 13,



Token is the fundamental unit used by Apache Lucy’s Analyzer subclasses.
Each Token has 5 attributes: C<text>, C<start_offset>,
C<end_offset>, C<boost>, and C<pos_inc>.

The C<text> attribute is a Unicode string encoded as UTF-8.

C<start_offset> is the start point of the token text, measured in
Unicode code points from the top of the stored field;
C<end_offset> delimits the corresponding closing boundary.
C<start_offset> and C<end_offset> locate the Token
within a larger context, even if the Token’s text attribute gets modified
– by stemming, for instance.  The Token for “beating” in the text “beating
a dead horse” begins life with a start_offset of 0 and an end_offset of 7;
after stemming, the text is “beat”, but the start_offset is still 0 and the
end_offset is still 7.  This allows “beating” to be highlighted correctly
after a search matches “beat”.

C<boost> is a per-token weight.  Use this when you want to assign
more or less importance to a particular token, as you might for emboldened
text within an HTML document, for example.  (Note: The field this token
belongs to must be spec’d to use a posting of type RichPosting.)

C<pos_inc> is the POSition INCrement, measured in Tokens.  This
attribute, which defaults to 1, is a an advanced tool for manipulating
phrase matching.  Ordinarily, Tokens are assigned consecutive position
numbers: 0, 1, and 2 for C<"three blind mice">.  However, if you
set the position increment for “blind” to, say, 1000, then the three tokens
will end up assigned to positions 0, 1, and 1001 – and will no longer
produce a phrase match for the query C<"three blind mice">.
