Information retrieval

Recall is

a measure of the effectiveness of document retrieval expressed as a ratio of the total number of relevant documents in a given database (or on the Web) to the number of relevant entries or documents retrieved in response to a specific search. However, determining a search's recall can be problematic because it is often very difficult to determine the total number of relevant entries in all but very small databases.[2]
