Thanks so much for your reply Mr.Miller, that's exactly what I was trying to
accomplish! :-)
I have however, run into another problem now, and thus I have a follow up
question:
My goal is to provide a set of results like google to the user that presents
a set of results with the keyword highlighted along with about two lines of
text surrounding it. When the user clicks on this link, they should be able
to see the entire block of text with the highlighted keyword on the next
page. I have found that I am able to do one or the other (i.e. retrieve the
entire block of text with the highlighted keyword, or the highlighted
keyword and just the surrounding text, but not both at the same time).
My code where I am trying to do this is as follows:
QueryScorer scorer = new QueryScorer(parser);
Highlighter highlighter = new Highlighter(scorer); //reference to
highlight the keyword in the entire block of text
Highlighter high = new Highlighter(scorer); //reference to highlight
the keyword in the surrounding text
Fragmenter fragmenter = new NullFragmenter(); //reference to retrieve
the entire block of text
Fragmenter fragment = new SimpleFragmenter(250);// reference to
retrieve the surrounding text
highlighter.setTextFragmenter(fragmenter);
high.setTextFragmenter(fragment);
for(int i=0; i<hits.length(); i++){
Document doc=hits.doc(i);
String lns = doc.get("LINES");
TokenStream lines = analyser.tokenStream("LINES", new
StringReader(lns));
String highlightedLines = highlighter.getBestFragment(lines, lns);
String highlight = high.getBestFragment(lines, lns);
SearchResult resultBean = new SearchResult();
resultBean.setNarrator(hits.doc(i).get("SPEAKER"));
resultBean.setQuote(highlightedLines);
resultBean.setHitResult(highlight);
searchResult.add(resultBean);
System.out.println(resultBean.getNarrator());
System.out.println(resultBean.getHitResult());
System.out.println("");
//System.out.println(resultBean.getQuote());
System.out.println("");
System.out.println("");
System.out.println("");
}
System.err.println("Found " + hits.length() + " document(s)(in " +
(end-start) + " milliseconds) that matched query '" + q + "':");
return searchResult;
}
How would I accomplish this? Based on my above code, what am I doing wrong?
My code retrieves the entire block of text with the highilghted keyword
correctly, but I am getting null as my output when I try to print the
results of the highlighted keyword and the surrounding text.
Thanks again for all of your help.
Sincerely;
Fayyaz
