Not able to search KM Document with title

 Dear Team,

We have uploaded one KM document in HPSM---- KM area.
During the upload of document we have mention the title name as "Incident Report_03122012". Our customer requirement is  like if we search with the end date that document needs to find in KM. We are not able to find the document by mentioning the end date like "03122012"
Kindly help us to search the document with any text from title as well.
Regards,
EMS Team
