There are two types of search engines 1. Hybrid search engines 2. Meta search engines
Spider-Based Search Engines. Directory-Based Search Engines. Link-Based Search Engines.
Search engines allow you to answer questions quickly. You can simply type in your question, or a topic that you need information about, and a search engine will pull together some relevant webpages for you to look at that will hopefully answer your question. Using search engines has become much faster than looking answers to simple questions up in books or encyclopedias. However, for formal or academic research, books are still very valuable for the wide breadth of information they provide.
There are primarily three types of search engines: traditional search engines, vertical search engines, and meta-search engines. Traditional search engines like Google and Bing index the entire web and return results based on algorithms. Vertical search engines focus on specific niches or industries, such as medical or academic searches. Meta-search engines aggregate results from multiple search engines to provide a broader range of information.
Horizontal search engines are general-purpose search engines such as Google and Yahoo. Vertical search engines, meanwhile, are specialized by content such as Trulia, Mocavo and Yelp.
