I create an IndexWriter, index and then close the IndexWriter.
Then if I delte the index files it does this great.
try
{
FSDirectory dir = FSDirectory.getDirectory(directory);
for(String fileName : dir.list())
{
dir.deleteFile(fileName);
}
}
catch(IOException ioe)
{
ioe.printStackTrace();
}
But if in between creating index and deleting, I create a multi-searcher,
and close, I get IOExceptions when trying to delete the index.
private MultiSearcher initSearcher(Collection<Directory> indexes)
throws CorruptIndexException, IOException
{
IndexSearcher[] searchers = new IndexSearcher[indexes.size()];
Iterator<Directory> it = indexes.iterator();
int i = 0;
while (it.hasNext())
{
searchers[i] = new IndexSearcher(it.next());
i++;
}
return new MultiSearcher(searchers);
}
private void close()
{
try
{
searcher.close();
if(searcher instanceof MultiSearcher)
{
MultiSearcher ms = (MultiSearcher)searcher;
ms.close();
for(Searchable s
:Arrays.asList(ms.getSearchables()))
{
s.close();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
