Ten essential tips for searching the Web

inding just the right page among the billions on the Web requires not only a search engine but also a bit of know-how. Here is a selection of my favorite tips for searching the Web.

1. Search for a phrase

To search for an exact, complete phrase and not just its constituent words, put it in quotation marks. For example, instead of typing at sunrise on my birthdaytype ”at sunrise on my birthday”. The number of hits will shrink dramatically, as you’ll see only pages that include that exact phrase.

2. Be more specific

If you want to find articles about managing bookmarks in Safari on an iPhone running iOS 7, don’t search for just manage bookmarks. Throw all those terms in: manage bookmarks safari iphone ios 7. The more information you provide, the more useful your results are likely to be.

3. Exclude a word

To make sure your search for information on the connector your iPhone uses doesn’t return matches about an atmospheric phenomenon or a fictional race car, put a hyphen (-) in front of terms that should disqualify a page from appearing in Google’s results—for example, lightning -thunder -storm -McQueen.
Get more specific by excluding certain words from your search.

4. Use your own words

If you visit Google.com in Google Chrome, you can click the microphone icon on the right side of the search field and speak your search terms out loud. As soon as you finish talking, Google displays matching results and sometimes offers a summary aloud.
In Google Chrome, go to the Google homepage, click the microphone icon (top), and start talking. Whatever you say appears on screen (bottom), followed shortly thereafter by matching search results.

5. Try an advanced search

If you want much more control over your searches, such as specifying which geographic regions to search in, how recently created a page should be, or the page’s reading level, go to Google’s Advanced Search page or, after performing a basic search, click the gear icon in the upper-right corner of the results page and choose Advanced Search from the pop-up menu.
Google’s Advanced Search page lets you fill out a form with options for a detailed, specific search.

6. Convert, calculate, and more

You can also use Google to find all sorts of information besides lists of webpages. Google can handle calculations (try 104 * 36.8), currency conversions (185 dollars in euros), time-zone conversions (time in Paris), weather forecasts (weather San Diego), word definitions (define: pedantic), and a great many other things.
You don’t need a calculator (or a calculator app) if you have a browser open.

7. Learn from the source

A great place to learn dozens of additional tips for using Google is Google itself. For example, Google’s “Basic search help” and “Tips & Tricks” pages have loads of tricks and shortcuts you can use.

8. Simplify Google URLs

One thing I’ve come to dislike about Google, however, is that the links on its results page are all Google URLs that redirect you to the original page. For example, if you search for macworld, the first hit is for www.macworld.com. However, if you try to copy the URL, it’ll look something like this:
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCwQFjAA&url=http%3A%2F%2Fwww.macworld.com%2F&ei=YL48UrOEPYbyQGA3ICIBg&usg=AFQjCNF8KJ4binisdLIm41H5qMrvHdQgw
And, depending on your browser, this sort of URL may also throw off your browsing history, making it difficult to see which sites you’ve been to.
Luckily, you can solve this problem with a browser extension. My pick for Apple’s Safari is Shaun Inman’s free Detox. (It was originally designed for Twitter, but it works great for Google, too.) For Google Chrome, first install the free Tampermonkey, and then add the script Scrub Google Redirect Links. For Mozilla Firefox, try Wladimir Palant’s free Google/Yandex search link fix.

9. Use another search engine

Even the best Google search won’t help you find pages that Google hasn’t indexed, or items that are on page 5987 out of 28,001. If Google isn’t cutting it, you have alternatives. Competitors, including Bing, Yahoo, Ask.com, and DuckDuckGo, may point you to sites that don’t show up in Google. And because each search engine prioritizes search results differently, the page you’re looking for may be more prominent in one than in another. If you get stuck, trying the same search in another engine may do the trick.

10. Try a metasearch

If you frequently need to search across multiple engines (and, perhaps, on highly specific databases that store information not indexed in general-purpose public search engines), you might be a good candidate for DevonAgent Pro (4 out of 5 rating), which can query many sites and services at once and summarize search results in a way that exposes connections between related concepts.

TOOLs for Editing photos

A good camera is not all that's required for fantastic snapshots. Some  free apps and software for it...
 
These simple tools will let you crop, rotate, and retouch your pictures, and will even let you add that extra tadka - photo frames and special effects - to your snapshots with a single click of your mouse button.



Pixlr 

Professionals might swear by Adobe Photoshop, but there are a whole bunch of users who've discovered the magic of an internet-based photo editor called Pixlr. This online tool, like any advanced image editor, comes with the layers option; over 25 graphic filters (blur, sharpen, diffuse, pixelate, emboss and engrave), a complete tool-set (stamp-clone, ink, eraser, magicwand, gradient-fill ), and even photo adjustment options (levels, curves, hue and saturation, brightness and contrast). All you have to do, is open the picture you want to edit in the app, work on it using the tools at your disposal, and then save the finished image back onto your machine.

Now, in case you're a first-timer, and find Pixlr too daunting, you could try out the simpler Pixlr Express or Pixlr-o-matic .

Express uses simple onetouch buttons to make adjustments in contrast and colour, to auto-fix your snapshots, and even rotate and resize them. Using this tool you can apply photo effects, add digital frames to your pictures and even overlay your images with text. Pixlr-o-matic simplifies things even further. Import a JPEG from your computer and you can apply readymade effects to your images. Simply select the effect you like and you're done. Pixlr Express, Pixlr-o-matic are also available as free apps for Android and iOS. pixlr.com

Picasa 3.9 



If you have a dodgy internet connection, then editing images online might not work out in your favour. Instead, it would be better if you made changes to your pictures using software on your PC before posting them to your web album or social network.

Picasa, which is a 14.3MB free download, lets you straighten and crop photographs, and then even lets you use filters, effects and quick fix tools like Auto Contrast, Auto Colour and Retouch. Creating a collage or a poster is just as simple, and takes just a few clicks.

People in group photos can also be tagged: tag a person in one snapshot, and Picasa's brilliant built-in face-detection algorithm takes over, identifying the same person in other images.

Additionally, this software comes with a 'batch edit' feature that lets you automate repetitive tasks across multiple files. Once you are done, images can be uploaded directly to your Google+ account (with the face tags intact), or exported to another folder, with a watermark. picasa.google.com

Be Funky 



What is life without options? If you're looking for a tool that's simpler than Pixlr, but more advanced than Pixlr Express and Pixlr-omatic, you might want to try Be Funky. This web tool simplifies the process of photo editing by offering users a ready-to-use library of special effects - nearly 30 of them - and you can even fix common photo problems like bad lighting, digital noise, fuzzy colours and details with a single click. Additionally, it lets you share your edited images directly on Facebook, Twitter, Tumblr and Flickr and even print if you have a printer at hand. The best part, you can take this tool with you on your smartphone - Be Funky has a fully-functioning app for Android and iOS devices. www.befunky.com
