Erik Hatcher commented on LUCENE-645:
-------------------------------------
There is some commented out code in Highlighter.java:
if (lastEndOffset < text.length())
newText.append(encoder.encodeText(text.substring(lastEndOffset)));
uncommenting that code fixes this issue.
I've added this test to HighlighterTest.java:
public void testOffByOne() throws IOException {
TermQuery query= new TermQuery( new Term( "data", "help" ));
Highlighter hg = new Highlighter(new SimpleHTMLFormatter(), new
QueryScorer( query ));
hg.setTextFragmenter( new NullFragmenter() );
String match = null;
match = hg.getBestFragment( new StandardAnalyzer(), "data", "help me
[54-65]");
assertEquals("<B>help</B> me [54-65]", match);
}
all tests pass even with that code uncommented. I'll commit if there are no
objections.
