Serch engine


Search Engine





***A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.
  1. Goggle.
  2. Bing.
  3. Yahoo.
  4. Ask.com.
  5. AOL.com.
  6. Baidu.
  7. Wolframalpha.
  8. DuckDuckGo
web search engine is generally described as the deep web.


***Four Tips to Help Make the Most of a Search
  1. Make your keywords as precise as possible. If you're looking for information on Tyrannosaurus rex, don't type in "dinosaurs." ...
  2. Use two or more keywords in your search. ...
  3. Make sure you spell the keywords correctly. ...
  4. Always try more than one search engine

Search engines function on the Internet by allowing Internet users to find specific information from the Web based on keyword criteria that is entered by the user.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

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 safe search engines for kids

The home page for Kiddle search engine
Young children are using the internet to search and find content more than they ever have before—but we can all understand some of the trade-offs that come with this technological advancement.
Typical search engines (think Google, Bing, etc.) do not default to kid-friendly settings, and it takes a lot of adult monitoring to make sure that nothing is appearing and getting clicked on that isn’t age-appropriate.
Luckily in recent years, more and more safe search engines for kids have been emerging. Today we are going to talk about four of the most popular safe and kid friendly search engines, and why they should be on your radar if you are a parent, teacher, or child development professional.

1. Kiddle

Kiddle.co is a “safe visual search engine for kids” developed by Google. It has all of the power and resources of Google, with all of the safe search filters that parents and educators need.
In addition to traditional web and image searches, they also have “Kimages” or popular kid images, and “Kpedia”, a kid’s version of Wikipedia. In addition, there is also a video search feature, a news search feature, and resources for parents and educators.
The bottom toolbar also has more information on kids’ safe search and keyword blocking, making the platform a very transparent and understandable alternative search option.
What is really awesome about platforms like Kiddle is that there are very different approaches to how content is displayed, depending on the word. For example, typing in the word “boob” will give kids this error message:
We can understand how this is limiting (what if a kid is genuinely curious about body parts in a scientific or sociological way?) However, as pointed out by Mashable, not all terms have this “oops, try again” landing page.
In fact, when the word “transgender” is searched there are definitions, “kids of trans” resources, and other helpful information for kids that may have first hand experience with transgender communities, or may just be genuinely curious about the term and people who identify as trans.

2. Wacky Safe

The Microsoft version of a kid-oriented safe search engine is called Wacky Safe, and it comes in the form of an app that is specially made for PCs and Android phones. I’m sure you will not be surprised to find out that it is rated E for everyone.
It claims to provide an “ultra-safe” environment so that parents and educators can be worry-free about children surfing the web. As with other safe search sites for kids it blocks inappropriate content and images, uses strict keyword filtering, and allows for searching of information that is “kid-friendly.”
The app also blocks and filters harmful websites that would typically be blocked by parental controls.

3. KidRex

KidRex has to be one of my favorites—if for no other reason than because the home page contains a wonderfully drawn image of a T-rex.
This search engine, which is also powered by Google, is an independent organization that claims to be kid-centric with their “safe search for kids, by kids slogan.”
The organization (a division of Brent Media) was founded in 2016, and as you would expect, it addresses all of the parent/educator concerns that are associated with children searching online.

4. Safe Search Kids

You may think you’re experiencing deja vu at this point, but here is yet another available safe search engine that is geared toward kids and utilizes the power of…you guessed it…Google! (Seriously, can any company come out swinging and outshine Google in this area?).
Safe Search Kids is a download that is also available as an app, and can deliver filtered search results when your kids use the internet. This search tool automatically activates Google Safe Search—and ultimately helps to keep kids from landing on websites that contain inappropriate content.
