NAME

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

SYNOPSIS

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

DESCRIPTION

KinoSearch'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 = KinoSearch::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 KinoSearch::Highlight::Formatter, used to perform the actual highlighting.
•
encoder - an object which subclasses KinoSearch::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.
