[jira] Created: (LUCENE-1752) incorrect snippet returned with SpanScorer

incorrect snippet returned with SpanScorer
------------------------------------------

                 Key: LUCENE-1752
                 URL: https://issues.apache.org/jira/browse/LUCENE-1752
             Project: Lucene - Java
          Issue Type: Bug
          Components: contrib/highlighter
    Affects Versions: 2.9
            Reporter: Koji Sekiguchi
            Priority: Minor


This problem was reported by my customer. They are using Solr 1.3 and uni-gram, but it can be reproduced with Lucene 2.9 and WhitespaceAnalyzer.

{panel:title=Query}
(f1:"a b c d" OR f2:"a b c d") AND (f1:"b c g" OR f2:"b c g")
{panel}

The snippet we expected is:
{panel}
x y z <B>a</B> <B>b</B> <B>c</B> <B>d</B> e f g <B>b</B> <B>c</B> <B>g</B>
{panel}

but we got:
{panel}
x y z <B>a</B> b c <B>d</B> e f g <B>b</B> <B>c</B> <B>g</B>
{panel}

Program to reproduce the problem:
{code}
public class TestHighlighter {

  static final String CONTENT = "x y z a b c d e f g b c g";
  static final String PH1 = "\"a b c d\"";
  static final String PH2 = "\"b c g\"";
  static final String F1 = "f1";
  static final String F2 = "f2";
  static final String F1C = F1 + ":";
  static final String F2C = F2 + ":";
  static final String QUERY_STRING =
    "(" + F1C + PH1 + " OR " + F2C + PH1 + ") AND ("
    + F1C + PH2 + " OR " + F2C + PH2 + ")";
  static Analyzer analyzer = new WhitespaceAnalyzer();
  
  public static void main(String[] args) throws Exception {
    QueryParser qp = new QueryParser( F1, analyzer );
    Query query = qp.parse( QUERY_STRING );
    CachingTokenFilter stream = new CachingTokenFilter( analyzer.tokenStream( F1, new StringReader( CONTENT ) ) );
    Scorer scorer = new SpanScorer( query, F1, stream, false );
    Highlighter h = new Highlighter( scorer );
    System.out.println( "query : " + QUERY_STRING );
    System.out.println( h.getBestFragment( analyzer, F1,  CONTENT ) );
  }
}
{code}
