Here's a rough example using a database:
Hits hits=searcher.search(q);
int numDocs=Math.min(10, hits.length());
Analyzer analyzer=new WhitespaceAnalyzer();
PreparedStatement ps=conn.prepareStatement("select
docText from myTable where pk=?");
for(int i=0;i<numDocs;i++)
{
//get the key from Lucene storage
int
rdbmsKey=Integer.parseInt(hits.doc(i).get("rdbmsKey"));
//pass it to RDBMS query
ps.setInt(1,rdbmsKey);
if(rs.next())
{
String docText=rs.getString(1);
TokenStream tokenStream =
analyzer.tokenStream("contents", new
StringReader(docText));
String hilite=
highlighter.getBestFragments(tokenStream,
docText,3,"...");
}
}
...finally
{
DBUtils.tidy(conn,ps,rs);
}
