This module stores all the pages crawled by the spider during a giant database known as the index. consider it because the index during a paper book: you discover a word and see that pages mention this word. The index isn't static, it updates anytime the crawler finds a replacement page or re-crawls the one already presented within the index. Since the quantity of the index is extremely giant it usually takes time to commit all the changes into the database. therefore one might say that an internet site has been crawled, however not however indexed.

3. The ranker (or search engine software). This half interacts with user and asks for a quest question. Then it sifts scores of indexed pages and finds all of them that are relevant to that question. The results get sorted by relevance and at last are shown to a user.
