An Introduction to Web Page Indexing
Search engine indexing gathers, parses, and stores data to support accurate and fast retrieval. An alternate name for the process in the context of search engines designed to find web pages on the Internet is web page indexing.
The objective of indexing web pages is to optimize speed and performance in finding appropriate documents for a search query. Without an index, the search engine has to scan every document in the corpus, which requires considerable time and computing power. There are a few types of indexing techniques.
Most of the search engine uses an inverted index that stores a list of the documents containing each word; the search engine can use direct access to find the documents associated with each word in the query, in order to retrieve the matching documents quickly.
The advantage of the other technique, forward indexing, is that it is better to quickly store the words per document than storing list of the documents for each word as in inverted indexing.
