NAME

       KinoSearch1::Highlight::Highlighter - create and highlight excerpts

SYNOPSIS

           my $highlighter = KinoSearch1::Highlight::Highlighter->new(
               excerpt_field  => 'bodytext',
           );
           $hits->create_excerpts( highlighter => $highlighter );

DESCRIPTION

       KinoSearch1's Highlighter can be used to select a relevant snippet from a document, and to surround
       search terms with highlighting tags.  It handles both stems and phrases correctly and efficiently, using
       special-purpose data generated at index-time.

METHODS

   new
           my $highlighter = KinoSearch1::Highlight::Highlighter->new(
               excerpt_field  => 'bodytext', # required
               excerpt_length => 150,        # default: 200
               formatter      => $formatter, # default: SimpleHTMLFormatter
               encoder        => $encoder,   # default: SimpleHTMLEncoder
           );

       Constructor.  Takes hash-style parameters:

       •   excerpt_field  -  the  name  of  the  field  from  which  to  draw  the  excerpt.  This field must be
           "vectorized".

       •   excerpt_length - the length of the excerpt, in bytes.  This should probably use characters as a  unit
           instead of bytes, and the behavior is likely to change in the future.

       •   formatter  - an object which subclasses KinoSearch1::Highlight::Formatter, used to perform the actual
           highlighting.

       •   encoder - an object which subclasses KinoSearch1::Highlight::Encoder.  All excerpt text  gets  passed
           through  the  encoder,  including  highlighted terms.  By default, this is a SimpleHTMLEncoder, which
           encodes HTML entities.

       •   pre_tag - deprecated.

       •   post_tag - deprecated.
