System.IO.IOException: read past EOF  at Lucene.Net.Index.IndexWriter.Init(Directory d, Analyzer a, Boolean create, Boolean closeDir,

IndexDeletionPolicy deletionPolicy, Boolean autoCommit, Int32 maxFieldLength, IndexingChain indexingChain, IndexCommit commit)

at Lucene.Net.Index.IndexWriter..ctor(Directory d, Analyzer a, Boolean create, MaxFieldLength mfl)

If the index partition failed to repair the corrupted partition several times. 

1. Check FTI.WLOG for exception, if there is any exception captured by Lucene, ie: read past EOF, go to step 2
2. Stop Full Text Index Service and Full Text Search Service, use LukeAll.jar tool to check the Lucene index directory.
   • If it shows corruption or cannot read the Lucene directory go to step 3
3. Stop all the AM services, backup the corrupted Lucene index folder and then delete it
4. Restart all AM services, includes Full Text Index and Full Text Search Services
5. Full Text Index will scan all the partitions every 2 minutes, the services will rebuild and backfill the missing Lucene directory after 2-5 minutes
