Each term (word or stem or root or phrase or descriptor or concept ...) has an entry (often found by hashing, through a trie, or with a B-tree) which points to all the occurrences of that term in the collection. Sometimes the entry points to a short record that contains the number of occurrences and a pointer to where the list of occurrences begins, in another data structure. Often the occurrences indicate documents, though they may identify every match inside any document.
