เรื่องการสืบค้นข้อมูล


กาสืบค้นด้วย google


Get the local time anywhere
What time is it in Bangkok right now? Ask Google. Enter simply what time is it to get the local time in big cities around the world, or add the locale at the end of your query, like what time is it hong kong to get the local time there.

Track flight status

Enter the airline and flight number into the Google search box and get back the arrival and departure times right inside Google’s search results.


Convert currency, metrics, bytes, and more

Google’s powerful built-in converter calculator can help you out whether you’re cooking dinner, traveling abroad, or building a PC. Find out how many teaspoons are in a quarter cup (quarter cup in teaspoons) or how many seconds there are in a year (seconds in a year) or how many euros there are to five dollars (5 USD in Euro). For the geekier set, bits in kilobytes (155473 bytes in kilobytes) and numbers in hex or binary (19 in binary) are also pretty useful.

Find music and comic books

Using a combination of advanced search operators that specify music files available in an Apache directory listing, you can turn Google into your personal Napster. Go ahead, try this search for Nirvana tracks: -inurl:(htm|html|php) intitle:”index of” +”last modified” +”parent directory” +description +size +(wma|mp3) “Nirvana”. (Sub out Nirvana for the band you’re interested in; use this one in conjunction with number 7 to find new music, too.) The same type of search recipe can find comic books as well.

Make Google recognize faces

you’re doing an image search for Paris Hilton and don’t want any of the French city, a special URL parameter in Google’s Image search will do the trick. Add &imgtype=face to the end of your image search to just get images of faces, without any inanimate objects. Try it out with a search for rose (which returns many photos of flowers) versus rose with the face parameter.

Google + Social Media Sites = Quality Free Stuff – If you are on the hunt for free desktop wallpaper, stock images, WordPress templates or the like, using Google to search your favorite social media sites is your best bet.  The word “free” in any standard search query immediately attracts spam.  Why wade through potential spam in standard search results when numerous social media sites have an active community of users who have already ranked and reviewed the specific free items that interest you.  All you have to do is direct Google to search through each of these individual social media sites, and bingo… you find quality content ranked by hundreds of other people.
  • Examples:
Google for Music, Videos, and Ebooks – Google can be used to conduct a search for almost any file type, including Mp3s, PDFs, and videos.  Open web directories are one of the easiest places to quickly find an endless quantity of freely downloadable files.  This is an oldie, but it’s a goodie!  Why thousands of webmasters incessantly fail to secure their web severs will continue to boggle our minds.


10 Tips For Google Image Search

Google Image Search could be used in many ways.

1. If you want to know if a person is a man or a woman and the name doesn’t help, do a search for the name.

2. If you don’t know the meaning of a word, the pictures may help you.

3. A better search for Flickr. Google uses information from other sites that link to Flickr photos, so you may find Google search better.

4. Find what’s interesting about a site, by looking at the pictures included. For example:wired.com.

5. Find a new wallpaper for your desktop by restricting your search to large images. You can automate this using an application.

6. Find random personal pictures, using standard file names from digital cameras.

7. Type the name of a painter and you can take an art class.

8. Install a Greasemonkey script so you can view the original version of the image directly by clicking on the thumbnail.

9. Find the color of a word. “Word Color is a windows program that uses Google Image Search to determine the color of a word or string of words. It goes out there, retrieves the top 9 images and loops through all pixels, calculating the average hue, which is later converted to a color.”

10. If you want to grab search results, GoogleGrab is a tool that downloads images from Google Image Search. It even supports batch search.
