NAME

       Lucy::Highlight::Highlighter - Create and highlight excerpts.

SYNOPSIS

           my $highlighter = Lucy::Highlight::Highlighter->new(
               searcher => $searcher,
               query    => $query,
               field    => 'body'
           );
           my $hits = $searcher->hits( query => $query );
           while ( my $hit = $hits->next ) {
               my $excerpt = $highlighter->create_excerpt($hit);
               ...
           }

DESCRIPTION

       The Highlighter can be used to select relevant snippets 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.

CONSTRUCTORS

   new( [labeled params] )
           my $highlighter = Lucy::Highlight::Highlighter->new(
               searcher       => $searcher,    # required
               query          => $query,       # required
               field          => 'content',    # required
               excerpt_length => 150,          # default: 200
           );

       •   searcher - An object which inherits from Searcher, such as an IndexSearcher.

       •   query - Query object or a query string.

       •   field - The name of the field from which to draw the excerpt.  The field must marked
           as be "highlightable" (see FieldType).

       •   excerpt_length - Maximum length of the excerpt, in characters.

METHODS

   create_excerpt(hit_doc)
       Take a HitDoc object and return a highlighted excerpt as a string if the HitDoc has a
       value for the specified "field".

   highlight(text)
       Highlight a small section of text.  By default, prepends pre-tag and appends post-tag.
       This method is called internally by create_excerpt() when assembling an excerpt.

   encode(text)
       Encode text with HTML entities. This method is called internally by create_excerpt() for
       each text fragment when assembling an excerpt.  A subclass can override this if the text
       should be encoded differently or not at all.

   set_pre_tag(pre_tag)
       Setter.  The default value is "<strong>".

   get_pre_tag()
       Accessor.

   set_post_tag(post_tag)
