I'm trying to query a large index using Lucene.NET (version 2.9.2.1).
The index contains ~1.2 Million docs and its size is 1.7GB
When trying to open an IndexSearcher, I get the following Exception:
Lucene.Net.Index.CurruptIndexException - {"Incompatible format version: 2
expected 1 or lower"}
at Lucene.Net.Index.SegmentInfos.FindSegmentsFile.Run(IndexCommit commit)

The strange thing is, that I can open the index for writing/updating, and I can
also open the index using Luke, and query it.
I tried to optimize the index using Luke, but it did not do any good.
When I rebuild this index with a subset of the data, for example only 500K or
750K of documents, I can open and query it successfully... but somewhere over
1M docs, something goes wrong.
I'm running VS2010, on .NET 4.0, using 64bit machine over Win7Pro.
Thanks,
