The document-specific searches are designed to assist you with additional search criteria for particular transactional e-docs. In addition to the standard search criteria available in the basic or advanced search, these searches include unique fields such as document status, and document-specific reference numbers.
Example
The All My Proposals link from the Proposals menu group on the Researcher menu is a document-specific search for only Proposal documents that you have initiated.
