Hi,
I have some problems working with BinaryDocValues. The code below works
well with a few thousands of documents, but with more than 65000
documents it does not return the correct BinaryDocValues after the docId
(with docBase rebasing) reaches a certain id. From this point on, it
cycles returning the BinaryDocValues of first docs. I'm working wiht
lucene/solr 4.3.
I tested this code indexing 100000 documents, each with a
"binary_ids_campaigns" value equal to docId. After docId 65500 aprox. it
return BinaryDocValues corresponding to first doc ids. I have followed
the API instructions on how to rebase the docId, but I guess I'm missing
something. If someone could point me in the right direction, I would
really appreciate it.
Best regards,
Xavier
