I'm trying to use Highlighter with QueryScorer after reading:
https://issues.apache.org/jira/browse/LUCENE-1685
The problem is: I'm not getting a result unless my the query term is an exact
match. Am I missing filters? Is there a more complete example of how this
should work?
String content = "Global Climate Change affects us all";
String field = "content";
BooleanQuery query = new BooleanQuery();
// Unstemmed, matched case works
//query.add(new TermQuery(new Term(field, "Climate")),
BooleanClause.Occur.MUST);
// Stemmed, lowercase doesn't work
query.add(new TermQuery(new Term(field, "climat")),
BooleanClause.Occur.MUST);
query.add(new TermQuery(new Term(field, "affect")),
BooleanClause.Occur.MUST);
Highlighter highlighter = new Highlighter(new QueryScorer(query, field));
highlighter.setMaxDocCharsToAnalyze(500000);
TokenStream ts = htmlStripAnalyzer.tokenStream(field, new
StringReader(content));
ts = new CachingTokenFilter(ts);
System.out.println(highlighter.getBestFragment(ts, content));
Thanks for any feedback,
Justin
