How do you search some specific information on the internet? Just typing some words in  Google or Bing? No, no, no, you need more specific skills.

Here’s some useful tips for you.

1. Using the right method

You must know what exactly results shown in the first pages before you type anything in the search engine. Then think about what word can describe the information most specifically. After think about this, you can start typing something in the search engine.

2. Using right conjunction

If you want to search some classified information in San Francisco, you need to type “San Francisco classifieds” (which is really means San AND Francisco AND classifieds"), if you type the words “San Francisco OR classifieds” the results would be much different.
3.Ignore some words.

Google with directly ignore some words like “what” “in” “how” “on”, so, when you are about search something you must remember this. For example, when I search some free classified Ads in New York, I would type the word  “Free classified Ads New York” instead of “Free classified Ads in New York”.

4.Other tips

Search for short sentences, you ban put the in quotation marks like “nothing comes of nothing”.

Search for one document type you can type the words like this “guidebook filetype:pdf”.

If you are wondering how many sites point to you own site, you can just type the word in the search engine like this “link:google.com”.

To translate a words into other language, you can just type “ translate hello to Japanese”.

If you want to know how much one dollar equals in Chinese Yuan, just type” 1 USD to CNY”, then you can get het answer.

There’s lots of useful tips when you’re using search engines, if you can use them in your daily search, it will helps a lot.

Now this is a gap in the market no one had seen before. Plucky Japanese start-up Real-f offers you the chance to ‘see yourself’ as never before.

For $2,500 (yes, really) – or $3,920 – the company takes digital stills of your face, then mounds them over a 3D model to create a hard vinyl chloride ‘face’.

The resulting model is called a 3DPF – 3 Dimensional Photo Form. If a face isn’t quite enough, then you can opt for a full head and shoulders.

The company describes its process as a ‘human photocopier’.

Oddly, it’s not the first start-up to offer human face masks featuring your own face – but it’s by far the most realistic.

Real-f claims you can discern individual blood vessels and irises in the models.

‘We have progressed from monochrome to color, now is the era of the 3D stereoscopic effect,’ it says.

The one thing Real-f fails to address is what the point of it all might be – except to suggest that you could put the ‘head’ model (about twice the price of a mask) on top of a mannequin.

Whatever you use them for, expect to wait two weeks for deliver.
