highlighting

[Stelios Eliakis]

Hi,
I'm new to lucene and I'm interesting in highlighting.
I want to extract the Best Fragment (passage) from a text file.
When I use the following code I take the first fragment that contains my
query. Nevertheless, the JavaDoc says that the function getBestFragment
returns the best fragment. Do I something wrong?

   QueryScorer scorer = new QueryScorer(query);

   SimpleHTMLFormatter formatter =new SimpleHTMLFormatter("<span
class=\"highlight\">","</span>");

   Highlighter highlighter = new Highlighter(formatter, scorer);

   Fragmenter fragmenter = new SimpleFragmenter(50);

   QueryScorer fragmentScore=(QueryScorer) highlighter.getFragmentScorer();

   TokenStream tokenStream = new StandardAnalyzer().tokenStream("contents",
new StringReader(text));

   String result = highlighter.getBestFragment(tokenStream,text);

   System.out.println(result);


Thanks in advance
