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