Monday is the National holiday in Japan. I think they will test on Tuesday.

----------------------------------------
The patch looks good! Thanks, Mark.
I think the customer will test the patch with their data on uni-gram
environment on Monday. I'll report back. Thanks again. :)
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
Assignee: Mark Miller
Priority: Minor
Attachments: LUCENE-1752.patch
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}
