This seems like a better question for lucene-user list.
Why not just deal with IndexSearcher?
Here's a sample code I wrote a while ago:
private static final String _paIndexDir =
System.getProperty("foo.index.dir");
private static long _paIndexLastMod = 0L;
private static IndexSearcher _paIndexSearcher;
private static final Analyzer _analyzer = new PorterStemAnalyzer();
....
....
try
{
// if the index has been modified since opened, re-open it.
if (IndexReader.lastModified(_paIndexDir) >=
_paIndexLastMod)
{
_paIndexLastMod = new Date().getTime();
if (_paIndexSearcher != null)
_paIndexSearcher.close();
_paIndexLastMod = new Date().getTime();
_paIndexSearcher = new IndexSearcher(_paIndexDir);
}
}
catch (IOException e)
{
_log.error("Could not open/close IndexSearcher: " +
e.getMessage());
// ...
}
_paIndexDir is an instance of String.
