Hey All.
I'm running problems with document deletion. I tried to use
DeleteDocuments() and DeleteDocument() methods, both are with problems,
according explained below:
1) DeleteDocuments(term)
This simply doesn't delete anything from the Index.
//see the code sample:
//"theFieldName" was previously stored as Field.Store.YES and
Field.Index.TOKENIZED.
Term t = new Terms("theFieldName", "theFieldContent");
objIndexReader.DeleteDocuments(t);
I ask: Am I doing anything wrong here?
2) DeleteDocument(numDoc) <== this problem is a woot problem
After being frustrated ( :P ) with DeleteDocuments(), I ran to test
DeleteDocument(). Then I made a query to return a Hits collection. I did a
loop through the Hits collection and I called DeleteDocument(docNum) for
every document in the Hits collection.
Lets talk about the problem now..... this method DOES delete a document from
Index, BUT, it is actually deleting wrong documents. I noticed that instead
of deleting the documents found by the Hits collection, it is deleting the
documents based in its insertion order!!
I mean, if I call objIndexReader.DeleteDocument(0), it will delete the first
document from the entire INDEX, not the first document in the Hits
collection. So, it deleted the first documents I have inserted some days
ago, in previous indexing sessions.
I ask: is there a way to get the correct docNum from the document retrieved
in the Hits collection?
OR: is there a safe way to delete documents
OR: what I'm doing wrong?
Thanks in advance.
Cesar
