| An index is a huge collection of documents and information stored by search engines from which they perform a search. The bigger the search engine the more they will have in their index. A search engine performs a search using a reverse index as it looks for matching words and return results based on this relevancy vector. If you are looking for a closer match, semantic analysis and stemming allow for this. An index can also be the root of a file folder which is located on a web server. |
