Searching Documents with Paging concept in FileNet Content Engine

PageIterator (Paging)  (FileNet Content Engine API)

Provides paging functionality for sets of independent objects and repository rows.


Sets of independent objects and repository rows are divided into pages;each page is a number of collection elements (objects or rows) that represent a subset of the collection elements. You can iterate a page at a time instead of one object or row at a time. 

As an example, if a page is defined as 10 elements, and the collection has a total of 22 elements, the first paging operation returns a page containing 10 elements, the second page returns the next 10 elements, and the third page returns the last 2 elements. This page iteration is especially useful for interactive applications that display a page of information at a time.
