Explanation / Answer

1. Understand Internet search tools.

a. Define Search query.

Search query is the query formed by the search engine in order to provide a response
to the given string searched in the search engines like google.Web search queries are
distinctive in that they are often plain text or hypertext with optional search-directives.
They vary greatly from standard query languages, which are governed by strict syntax rules
as command languages with keyword or positional parameters.

b. Describe search engines and how they work.

Search engines are the programs written to extract the query string searched in the world wide web using
programs call web crawlers.Web Crawlers use the query string as the index.Search engines don't function
on the Internet, but they provide databases for people who are seeking information that can be found on the Web.

Search Engines use meta tags to detect a websites which contains the searched query.Meta tags are nothing but
specific keywords and concepts that the owner of the websites specify.Based on these meta tags web crawlers
find the webpages related to the query string and the information is stored with the data.And using some
algorithms search engines rank the searched pages and display it to the user.

c. Explain how metasearch engine works.

Metasearch engines unlike other search engines do not store the data searched from the search query instead
they search from the results of other search engines and apply their own ranking to display the most relevant
page first.The meta search engines work by using the search string that you enter into the site engine to
query more than one search engine database.Meta search engines employ a virtual database method by using a
query to search other search engines where the actual databases are located.Meta search engines combine
the information and employ the services of the database-driven search engines to deliver links.
In Short-"You fire a query and meta engine starts pulling relevant results from different search engines,
compiles them, and returns the best results available from different search engines."

d. Describe how you find information on the deep web.

The Deep Web refers to the non-indexable content on the Internet, largely stored in publically available databases.
The Deep Web contains detailed information on specific topics, but this information is harder to access because
it’s not laid out on Web pages.Technically, this is not a difficult process. You simply need to install and use Tor.
Go to www.torproject.org and download the Tor Browser Bundle, a specialized piece of software designed for private,Deep Web sites. TOR stands for “The Onion Router,” and it’s a system for anonymous online browsing,but don't use TOR not unless you are sure that you know what you’re doing.

e. Explain how using a social media search engine is different from using a metasearch engine.

Social Media Search Engines basically searches not only for the keyword provided in the search query but it also
try to find relations between the results and the searcher.Relations simply means some sort of connection.
for example: LinkedIn may use relations like if the result and the searcher are in the same company, same industry,similar aspirations etc.
They are different than the metasearch engines as metasearch engines use relevance as meta tags not as the relations between the result and the searcher.Moreover metasearch engines use only semantic relevance which is not always the required by the user.
