Lemur 2.2.1 release notes

• We have tested using gcc 3.2.3 and VC++.
  
  
• This version includes minor fixes from the major release version 2.2.
  Please see release notes for 2.2 for explanation of new features.
  
  

• Bugs Fixed:
  1. Problem: KeyfileIncIndex fails with long termids or docids.
     Solution: Increase id length limit to 256 characters and check for it before adding.
  2. Problem: #BAND structured query operator returns incorrect value with OOV terms.
     Solution: change StructQueryRep::getChildren to count OOV child nodes.
  3. Problem: resultFormat parameter string incorrect in RetParamManager
     Solution: fix string
  4. Problem: OdnQnode::orderedProxList overruns an array, corrupting memory
     Solution: fix to disallow a node from participating in more than one matching window
  5. Problem: File::appendSegment opens file in write only mode
     Solution: modify to open in read and write mode
  6. Problem: cannot get to RM2 feedback method for SimpleKLRetMethod
     Solution: fix SimpleKLParameter to set qryPrm.fbMethod correctly for RM2 case.
  7. Problem: KeyfileIncIndex seg faults during index merge phase
     Solution: fix KeyfileIncIndex to check for empty segment files
  8. Problem: FlattextDocMgr returns self for method getTextHandler
     Solution: remove unnecessary method in order to default to TextHandler specification behavior
