>> Is that the same reader that is used in IndexSearcher?
I opened an IndexSearcher on the path (String) to the index.
Now I tried to open on the clone IndexReader and use the constructor
that has an IndexReader as param,
and I got everything working now ....
I just have two IndexSearchers opened now most of the time, which is
deprecated,
But I think that's my only choice !
Thank u !

Isn't the code snippet below doing a search before attempting the
deletion, so
from the IndexReader's point of view (as used by the IndexSearcher) the
item
exists. What is mIndexReaderClone? Is that the same reader that is
used in
IndexSearcher?
I'm not sure, but if you search with one IndexReader and delete the
document
using another IndexReader and then repeat the process, I think that the
search
would still result in a hit, but the deletion would return 0.
