The document discusses different types of search engines. It describes crawler-based search engines like Google, Bing, and Yahoo that use bots to crawl and index websites. It also mentions human-powered directories that rely on human submissions and reviews of website descriptions and categories. Finally, it discusses hybrid search engines that use both crawlers and human indexing, and how Google is an example of a hybrid search engine.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. ONLINE RESEARCH
is the practice of using Internet information, especially free
information on the World Wide Web, or Internet-based
resources (like Internet discussion forum) in research.
Internet research has had a profound impact on the way
ideas are formed and knowledge is created. Common
applications of Internet research include personal research
on a particular subject (something mentioned on the news,
a health problem, etc.), students doing research for
academic projects and papers, and journalists and other
writers researching stories.
3. THE SEARCH ENGINE
Search engines are programs that search
documents for specified keywords and returns a list
of the documents where the keywords were found. A
search engine is really a general class of programs,
however, the term is often used to specifically
describe systems like Google, Bing and Yahoo!
Search that enable users to search for documents
on the World Wide Web.
4. TYPES OF SEARCH ENGINE
• Crawler Based Search Engines
All crawler based search engines use a crawler or bot or
spider for crawling and indexing the new content to the
search database. There are four basic steps which every
crawler based search engines follow before displaying
any sites in the search results.
Example of crawler based search engines:
• Google
• Bing
• Yahoo!
• Baidu
5. Human powered directories also referred as open
directory system depends on human based
activities for listings.
• Site owner submits a short description of the site to the
directory along with category it is to be listed.
• Submitted site is then manually reviewed and added in the
appropriate category or rejected for listing.
• Keywords entered in a search box will be matched with the
description of the sites. This means the changes made to the
content of a web pages are not taken into consideration as it
is only the description that matters.
• A good site with good content is more likely to be reviewed
for free compared to a site with poor content.
6. Hybrid Search Engines
Hybrid Search Engines use both crawler based and
manual indexing for listings the sites in search
results. Most of the crawler based search engines
like Google basically uses crawlers as a primary
mechanism and manual screening as a secondary
mechanism. When a site is being identified for
spammy activities, manual review is required before
including it again in the search results.
7. Other Types of Search Engines
https://www.webnots.com/what-are-different-types-of-search-engines/
• Search engines have different types of bots for exclusively
displaying images, videos, news, products and local listings. For
example, Google News page can be used to search only news
from different newspapers.
• Some of the search engines like Dogpile collects meta
information of the pages from other search engines and
directories to display in the search results. This type of search
engines are called metasearch engines.
• Semantic search engines like Swoogle provide accurate search
results on specific area by understanding the contextual
meaning of the search queries.
8. A bot (short for "robot") is a program that operates
as an agent for a user or another program or
simulates a human activity. On the Internet, the
most ubiquitous bots are the programs, also called
spiders or crawlers, that access Web sites and
gather their content for search engine indexes.
10. GOOGLE BOOLEAN
OPERATORS
Boolean methods can be used on
any search engine: Google,
LinkedIn, or even Facebook.
Boolean is a term used to define
the process of combining
keywords with words called
“operators.” These operators tell
the search engine how to use the
keywords in the search. Operator
word examples are AND, NOT,
and OR.
