Hi,
I have put this question as "urgent" because I can notice I don't have
often answers,
If I'm asking the wrong way, please tell me...
Before I delete a document I search it in the index to be sure there is
a hit (via a Term object),
When I find a hit I delete the document (with the same Term object),
But there is something very odd happing sometimes :
I find a hit, but the integer returned by deleteDocuments is equal to 0
This often happens after I merged the index for the first time,
it never happens before I merge ...
Term urlTerm = new Term("url", urlToDel);
Query query = new TermQuery(urlTerm);
Hits hits = search(query);
if (hits.length() > 0) {
if (hits.length() > 1) {
System.out.println("found in the index with
duplicates");
}
System.out.println("found in the index");
try {
int nb = mIndexReaderClone.deleteDocuments(urlTerm);
if (nb > 0)
System.out.println("successfully deleted");
else
throw new IOException("0 doc deleted");
} catch (IOException e) {
e.printStackTrace();
throw new Exception(
Thread.currentThread().getName() + " ---
Deleting old entry failed",
e);
}
What I get sometimes is :
found in the index
0 doc deleted
