Hello,

Do these 2 exceptions look familiar to anyone:

The second exception that I am getting is this:

at org.apache.lucene.search.Searcher.search(Searcher.java:69)


Any search I make in a multi-threaded environment seems to fail withone
of these exceptions.
The search code in use looks like this:

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();
}
if (_paIndexSearcher == null)
_paIndexSearcher = new IndexSearcher(_paIndexDir);
}
catch (IOException e)
{
_log.error("Could not open/close IndexSearcher: " +
e.getMessage());
return;
}

Query query = null;
Hits hits = null;
try {
query = MultiFieldQueryParser.parse(queryString, new String[]
{"title", "description"}, _analyzer);
hits = _paIndexSearcher.search(query);
} catch (ParseException e) {
_log.warn("QueryParser threw ParseException while parsing: " +
queryString, e);
} catch (TokenMgrError e) {
_log.warn("QueryParser threw TokenMgrException while parsing: " +
queryString, e);
} catch (IOException e) {
_log.error("IndexSearcher threw IOException while searching for: "
+
queryString, e);
}

I'm about to look at the source, but if any of these exceptions look
familiar to anyone, or if you see a flaw in the code above please let
me know.

Thanks,
Otis
