Subject Re: Bad file descriptor (IOException) using SearchBean contribution
Date Tue, 18 May 2004 16:30:20 GMT
Lucene 1.4 (now in release candidate stage) includes built-in sorting  
capabilities, so I definitely recommend you have a look at that.   
SearchBean is effectively deprecated based on this new much more  
powerful feature.
