Search functionality should search the documents by only its Name, not the content

Hi,

When I search for particular document name in SharePoint then it displays multiple results. I think, search functionality will search document content as well. I need search functionality only should search the documents by its Name, not the content. How can I set this functionality. I am on MOSS 2007.

Any solution approach to this. Experts can you answer

Thanks,
