----------------------------------
Hi Mark, sorry for the long time missing!
Here is the test, it fails again with the lastest version (Revision 450719):
Expected :A<B>BC</B>DE<B>FG</B>HIJ
Actual:A<B>BCDEFG</B>HIJ
public void testOverlapAnalyzer4() throws Exception
{
String s = "ABCDEFGHIJ";
// the token stream for the string above:
TokenStream ts = new TokenStream() {
Iterator iter;
{
List lst = new ArrayList();
Token t;
t = new Token("AB",0,2);
lst.add(t);
t = new Token("BC",1,3);
lst.add(t);
t = new Token("CD",2,4);
lst.add(t);
t = new Token("DE",3,5);
lst.add(t);
t = new Token("EF",4,6);
lst.add(t);
t = new Token("FG",5,7);
lst.add(t);
t = new Token("GH",6,8);
lst.add(t);
t = new Token("HI",7,9);
lst.add(t);
t = new Token("IJ",8,10);
lst.add(t);
iter = lst.iterator();
}
public Token next() throws IOException {
return iter.hasNext() ? (Token)iter.next() : null;
}
};
String srchkey = "BC FG";
QueryParser parser=new QueryParser("text",new WhitespaceAnalyzer());
Query query = parser.parse(srchkey);
Highlighter highlighter = new Highlighter(new QueryScorer(query));
// Get 3 best fragments and seperate with a "..."
String result = highlighter.getBestFragments(ts, s, 3, "...");
String expectedResult="A<B>BC</B>DE<B>FG</B>HIJ";
assertEquals(expectedResult,result);
}
> highlighter problems with overlapping tokens

> Key: LUCENE-627
> URL: http://issues.apache.org/jira/browse/LUCENE-627
> Project: Lucene - Java
> Issue Type: Bug
> Components: Other
> Affects Versions: 2.0.1
> Reporter: Yonik Seeley
> Fix For: 2.0.1
>
> Attachments: highlight_overlap.diff, Highlighter.java.diff
>
>
> The lucene highlighter has problems when tokens that overlap are generated.
> For example, if analysis of iPod generates the tokens "i", "pod", "ipod"
> (with pod and ipod in the same position),
> then the highlighter will output this as iipod, regardless of if any of those
> tokens are highlighted.
