Custom Document Property Sets are user defined Meta Data sets that can be attached to folders and documents. They are used to further define the document or folder.
A common use for this feature is to allow documents to be searched based on custom information, rather than just their name or content.
Examples:
I want every invoice document where the invoice amount is more than $400.00Consider the example where you are looking for invoices in the amount of more than $400.00. You could easily find the invoices that have an exact invoice amount of $400.00 but what if you needed more than that?
Custom properties allow you to search in ranges. This is much more than a simple full-text search.
Custom Properties can be defined globally or at the library level. This allows you to create a custom document property set that only appears in one or selected libraries. This way, "Custom Property Sets" that do not apply to certain libraries can be hidden from view.
