Subject [jira] Commented: (LUCENE-627) highlighter problems with overlapping tokens
Date Thu, 13 Jul 2006 19:33:30 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-627?page=comments#action_12420915 ] 

Mark Harwood commented on LUCENE-627:
-------------------------------------

Works OK for me - just added this to the Highlighter's Junit test and all is well.
Something up with your analyzer?


	public void testOverlapAnalyzer2() throws Exception
	{
		HashMap synonyms = new HashMap();
		synonyms.put("ipod", "i,pod");
		Analyzer analyzer = new SynonymAnalyzer(synonyms);
		String srchkey = "ipod";

		String s = "I want an ipod";
		QueryParser parser=new QueryParser("text",new WhitespaceAnalyzer());
		Query query = parser.parse(srchkey);

		Highlighter highlighter = new Highlighter(new QueryScorer(query));
		TokenStream tokenStream =
			analyzer.tokenStream(null, new StringReader(s));
		// Get 3 best fragments and seperate with a "..."
		String result = highlighter.getBestFragments(tokenStream, s, 3, "...");
		String expectedResult="I want an <B>ipod</B>";
		assertEquals(expectedResult,result);
	}

> 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.
