RE: java.lang.IllegalArgumentException: attempt to access a deleted document

[Rob Outar]

I added the following code:

   for (int i = 0; i < numOfDocs; i++) {
                if ( !reader.isDeleted(i)) {
                    doc = reader.document(i);
                    docs[i] =
doc.get(SearchEngineConstants.REPOSITORY_PATH);
                }
            }
            return docs;

but it never goes in the if statement, for every value of i, isDeleted(i) is
returning true?!?  Am I doing something wrong?  I was trying to do what Doug
outlined below.


Thanks,

Rob

The limit of your iteration should be IndexReader.maxDoc(), not
IndexReader.numDocs():

http://jakarta.apache.org/lucene/docs/api/org/apache/lucene/index/IndexReade
r.html#maxDoc()

Also, you should first check that each document is not deleted before
calling IndexReader.document(int):

http://jakarta.apache.org/lucene/docs/api/org/apache/lucene/index/IndexReade
r.html#isDeleted(int)
