Mark Harwood commented on LUCENE-627:
-------------------------------------
Thanks for the test Kerang.
I no longer have a clear view as to what is expected behaviour here and whether
this is a test that needs to pass.
It seems to conflict with the expected results for Yonik's test method
"testOverlapAnalyzer2".
In that test, (like yours) for a cluster of overlapping tokens with search
terms identified at the beginning and end, Yonik expects the whole cluster from
search term 1's start offset to search term 2's end offset to be surrounded by
one highlight tag. Your test expected 2 tags.
Who is right?
This is a snippet from Yonik's test:
query = new QueryParser("text",new WhitespaceAnalyzer()).parse("hi speed");
highlighter = new Highlighter(new QueryScorer(query));
result = highlighter.getBestFragments(getTS2(), s, 3, "...");
assertEquals("<B>Hi-Speed</B>10 foo",result);
and yours:
String srchkey = "BC FG";
String expectedResult="A<B>BC</B>DE<B>FG</B>HIJ";
I don't really have an opinion either way so I'll turn it over to you
Cheers

> Issue Type: Bug

> 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.
