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.

Famous quotes containing the words comparison and/or search:
“In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (1817–1862)
“The danger lies in forgetting what we had. The flow between generations becomes a trickle, grandchildren tape-recording grandparents’ memories on special occasions perhaps—no casual storytelling jogged by daily life, there being no shared daily life what with migrations, exiles, diasporas, rendings, the search for work. Or there is a shared daily life riddled with holes of silence.”
—Adrienne Rich (b. 1929)
