Prospective search, or persistent search, is a technique of searching on the Internet where the question is given first and the data for the actual result are then acquired. This differs from traditional, or "retrospective", lookup such as search engines, where the subject matter for the results is got and then questioned.
Retrospective search starts up by collecting the information, indexing it, then allowing users query the data. The effect do n'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 supplying the results as they get. Typically Ping Servers are use to garner notification of alterations to websites so that the data been given is as fresh as possible. Users can be notified in a number of strategies to new outcomes.
