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 to, comparison and/or search:
“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
—Shusha Guppy (b. 1938)
“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)
“His life itself passes deeper in nature than the studies of the naturalist penetrate; himself a subject for the naturalist. The latter raises the moss and bark gently with his knife in search of insects; the former lays open logs to their core with his axe, and moss and bark fly far and wide. He gets his living by barking trees. Such a man has some right to fish, and I love to see nature carried out in him.”
—Henry David Thoreau (1817–1862)
