In a post-coordinate indexing system, a user can search for documents that contain a set of specified terms, regardless of the order in which they appear in the document. This is in contrast to a pre-coordinate indexing system, in which terms are assigned to specific positions within a document, and a user must specify the exact term and position to retrieve a document.
