Comparison To Retrospective Search
Retrospective search starts by gathering the information, indexing it, then letting users query the information. The results don't change until the index is rebuilt, often months apart. Prospective search starts with the user's queries, gathers the information in a targeted way, indexing it and then providing the results as they arrive. Sometimes Ping Servers are used to gather notification of changes to websites so that the information received is as fresh as possible. Users can be notified in a number of ways of new results.
Prospective search is well suited to queries where the results change over time, such as the current news, blogs and trends.

—Marianne E. Neifert (20th century)
