Rails uses /i on when creating the Regexp for matching in the highlight
options = args.extract_options!
unless args.empty?
options[:highlighter] = args[0] || '<strong class="highlight">\1</strong>'
end
options.reverse_merge!(:highlighter => '<strong class="highlight">\1</strong>')
if text.blank? || phrases.blank?
text
else
match = Array(phrases).map { |p| Regexp.escape(p) }.join('|')
text.gsub(/(#{match})(?!(?:[^<]*?)(?:["'])[^<>]*>)/i, options[:highlighter])
end
end
# Extracts an excerpt from +text+ that matches the first instance of +phrase+.
# The <tt>:radius</tt> option expands the excerpt on each side of the first occurrence of +phrase+ by the number of characters
# defined in <tt>:radius</tt> (which defaults to 100). If the excerpt radius overflows the beginning or end of the +text+,
# then the <tt>:omission</tt> option (which defaults to "...") will be prepended/appended accordingly. The resulting string
# will be stripped in any case. If the +phrase+ isn't found, nil is returned.
