Sunnetha,
this is my Search code... I have tried the get("body") call but it returns a Null.....
thus i cannot actually process document contents...... I need to do this to extract
data such as document titles etc
currently it uses get("path") to get the documents path but if I were to change that
to get("body") to System.out.print the contents it would print "Null"
anyway.. here is the code:
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.StopAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.search.Searcher;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.Hits;
import org.apache.lucene.queryParser.QueryParser;
public class Search {
public static void main(String[] args) throws Exception {
String indexPath = "index", queryString = "sharon";
Searcher searcher = new IndexSearcher(indexPath);
Query query = QueryParser.parse(queryString, "body",
new StopAnalyzer());
Hits hits = searcher.search(query);
for (int i=0; i<hits.length(); i++) {
System.out.println(hits.doc(i).get("path") + "; Score: " +
hits.score(i));
};
}
}

Hi Roshan,
U've got to get the contents as
doc(i).get("body")
The field name has to match what is queried back .
