Since the early days of the internet, there has not ceased to be the use of search engines to locate the myriads of information available online. The use of search engines is indispensable to locate the information you need. If you have used the Internet for up to 10 years and over, you would remember search engines like Lycos, AskJeeves, Altavista and so on. Even though these ones have faded out and more prominent search engines like Yahoo and Bing, which is powered by software giant Microsoft, have come to stay, none of them stands out or is as popular as Google.

Today, Google as a search engine is undoubtedly the number one, such the word, “Google” has been recognized as a verb in the Oxford dictionary used as a synonym for “search.”

Now that dependence on Google for is that high, it only makes sense for one to know how to get Google to provide exactly the kind of information they want. How is this done?

What follows is a list of formats which you can use to get Google to give you just what you want. These few tricks from will help you become a Google power user.

Search exact: 

If you are looking for an exact phrase, use quotation marks like this: “the evening of December 25”

Exclude a word:

Add a hyphen “-“ before a word to exclude a search term. This is useful if you are searching for a word with several meanings. For example, you could type: Terminator –movie, to get results for the word terminator apart from the movie.

Search within a site:

This is used to search for items but restricting the results to within a particular site. The keyword is “site:” For example, ebola

Related websites:

Find websites similar to one you already know. Keyword is “related:” for example, related:

Find news related to a particular location:

Use this on Google news to find stories coming from a particular location. Keyword to use is “location:” For example, disease outbreak location:Lagos

Search for a particular file type:

If you are looking for files of a particular file format use the keyword, “filetype:” followed immediately by the file type such as doc, pdf, xls. An example is, “2014 curriculum filetype:pdf”

Using asterisk sign:

The asterisk * sign is used as a wildcard and helps you find a missing word in a phrase. For example, “the effects of * petrol”

Using OR

If you want to find pages with one of several words, use a capitalized OR. Without OR, results will show pages that include all the terms. An example is, “World Cup 2014 OR 2010”

More kkeywords that exist in Google search are: WEATHER, example, weather:Abuja; TIME, example, time:London; APPL for stock quotes; and DEFINE for definitions, for example, define jingoisms.

Aside from the examples above, Google does not usually recognize punctuation or grammar. However, punctuation and symbols that do work in Google search include: @, #,  $, +,  for searching social tags,  hash tags, prices and blood type respectively.

Google has other services to give you results tailored to your needs such as Google Images for searching for pictures related to a particular word or phrase you enter; you can also upload an image to find out more about it.

Google Goggles lets you search the web using your mobile phone’s camera instead of words. Simply take a picture of the item you want to search for and look at the results.

Google Trends lets you explore trending search topics on Google and see what other people are searching for.

Google Books lets you search and preview books from millions of publishers around the world.

Google Scholar lets you search for theses, abstracts and articles.

Instagram plans to offer high-profile influencers special tools that will provide them with a deeper insight into various data regarding their followers. These tools will be delivered in the form of Creator Accounts, which will only be available to select Instagram users (i.e. influencers, celebs).

An Instagram official recently told The Hollywood Reporter that the company wishes to make sure that “Instagram is the best place, and easiest place, to build fan communities and also build creators. personal brands.”

These creator accounts are meant to function like business-focused profiles and will offer growth insights, including information about follows and unfollows. Influencers will also be able to see weekly and daily data about their followers count changes so that they can better understand what might have caused a decline in their fan base or a spike in new followers.

Also, direct messaging tools that will enable Instagram users to filter notes from brand partners and friends will be available as well. Furthermore, influencers will be allowed to choose how they want to be contacted via flexible labels.

According to Instagram. these new features are being tested with a small beta group at the moment, but they are expected to be rolled out to everyone sometime in 2019.

Advertisements will finally be making its way into messenger service WhatsApp, in its ‘Status’ section.

Outlook India reports that WhatsApp’s vice-president Chris Daniels confirmed the move, though he did not provide a timeline for when it would be rolled out or how the ads would work.

“We are going to be putting ads in ‘Status’. That is going to be primary monetisation mode for the company as well as an opportunity for businesses to reach people on WhatsApp,” he said.

Like with Instagram stories, WhatsApp’s ‘Status’ feature lets users to broadcast text, photos and videos which disappear after 24 hours.

Users will be able to see status updates by their saved contacts in the ‘Status’ column, between ‘Chats’ and ‘Calls’.

WhatsApp has more than 1.5 billion global users and maintained its ad-free status until now, although it did experiment with an annual subscription fee several years ago.

Facebook Inc acquired the messaging apps four years ago for US$19bil (RM79.47bil) and it appears it’s finally going to monetise the service through ads.

WhatsApp cofounder Brian Acton had opposed monetisation via targeted apps, telling Forbes that it would compromise the assurance of encryption in the app’s messaging.

Samsung has created smart TV software you can control with your brainwaves.

The research, called Project Pontis, aims to make Samsung’s televisions more accessible for people with physical disabilities like quadriplegia. The company wants to enable “users with physical limitations to change channels and adjust sound volume with their brains.”

Samsung’s Swiss operations started the project three months ago in partnership with the Center of Neuroprosthetics of the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. The company demoed its second prototype TV on Thursday at its developer conference in San Francisco.

“How can we provide accessibility to people who cannot move or who have extreme limitations on their movements,” Ricardo Chavarriaga, a senior scientist at EPFL who’s working on the project with Samsung, said during a panel at Samsung Developer Conference.

“We’re making tech that is more complex, that is more intelligent, but we should not forget this tech is being made to interface with humans,” he added.

The first step in making the brainwave-controlled TV software is to collect a sample of how the brain behaves when the user wants to do something like select a movie. Samsung and EPFL combine indicators from both the environment and brain scans to build a model and apply machine learning to let the user select shows using eye movements and brainwaves.

To collect the brainwaves in the prototype, a user wears a headset covered with 64 sensors while looking at an eye tracker. The headset is connected to a computer that’s mirrored to the TV.

The current prototype uses eye tracking to determine when a user has selected a particular movie. The system then builds a profile of videos the user gravitates toward, making it easier to provide lists of content in the future. The user ultimately makes a selection using eye tracking.

Samsung and EPFL are also working on a system that goes further and relies on brain signals alone for users who aren’t able to control their eyes or other muscles reliably, Chavarriaga said.

“One thing we have to take in account is everybody is different,” he said. Currently, the technology has to be tailored to each person because of variations in brains. “We believe we have to do the best for the person, so we have to personalize,” Chavarriaga told CNET.

Samsung this week has been hosting its annual developer conference in San Francisco. SDC reflects Samsung’s big push to get developers to make software specifically for its devices. In the past, that’s meant making apps that work on the edge of Samsung’s curved smartphone displays or take advantage of its S Pen stylus. This year, that focus has turned to Bixby and artificial intelligence. But Samsung also has pushed developers to make apps for its other products, like its TVs and home appliances.

Brain power

While developers aren’t yet making apps that can be controlled with the brain, Samsung’s doing research into the area. And it’s not the only company trying to use brainwaves to control devices. SpaceX and Tesla CEO Elon Musk in March 2017 launched Neuralink, a company dedicated to creating “neural lace,” which involves installing tiny electrodes in the brain to transmit thoughts.

Samsung’s Project Pontis collects brainwaves to decide if the user wants to select a particular movie.

And neuroscientists around the globe have been researching ways to make a digital interface for the brain. The technology is still early days, but it could one day replace touch screens and voice assistants in devices. Currently, most brain-computer interfaces (BCIs) are currently being created only for people who have suffered debilitating injuries that left them partially or completely paralyzed.

While Samsung’s first prototype also is targeted at accessibility, it’s too soon to say whether we’ll all one day be controlling our devices with our brainwaves, said Martin Kathriner, head of public affairs for Samsung Electronics Switzerland GmbH. There are limitations with the current hardware. The sensor helmet requires a layer of gel applied to the head, something consumers likely aren’t going to do at home.

“To us it’s an accessibility idea,” he told CNET after Samsung’s SDC panel. “If it’s applicable to us one day as pro couch potatoes, I have no idea.”

Samsung initially considered building the technology into a smartphone but opted for the TV in part because of its bigger screen and because most homes have a TV, Kathriner said. He added that TVs also can be used as smart home hubs, which could be attractive for the brainwave technology.

Samsung plans to work on its second prototype through the first quarter of 2019 and then start tests in Swiss hospitals “where we start to explore how this situation, currently a prototype, … is perceived by patients,” Kathriner said.
