Remember these:

• Google default is to search for pages that include all of your search keywords .
• Google excludes common words (a.k.a stop words) like “the” , “He” etc.
• Google isn’t case sensitive, That is searching for wordpress is the same as WordPress.
• But Search operators are case sensitive, That is searching for wordpress OR joomla uses OR as the Google search operator, while wordpress or joomla doesn’t.
• Some operators may be combined, and some must be used alone.

Basic Search Operators

The basic Search operators which can be combine with your keywords easily are:

+

Forces words to be included in search results. Convenient with stop words that otherwise will be dumped

-

Prevents a search term to be included in the results, Like: searching for Automobile -cars won’t show the result for Cars in the Automobile search result page

OR

Returns with with one of the given terms, like Joomla OR Drupal. You might also use | instead of OR

” “

It is used to include all of the words given by you in search results, Remember to put the query within the “ ” . I use it to check copy and paste content.

~

Allows to search also for synonyms of the given keyword. like searching for wordpress ~tips finds also pages with the word help or guide etc.

*

Means every word to include(It’s a wildcard character) .

..

Used to search in a range of numbers

The above operators may be combined like, “Is WordPress better than Joomla OR Drupal”

Some more useful operators

define:

Used to return the definition of the given word like “define: guide”

filetype:

Restricts the results returned of a specific File Type. Like “Photoshop Guide filetype:pdf”

site:

Restricts the search results for a given web site only like “Google site:priteshgupta.com”

related:

Returns page that are related to the given page

info:

Gives information about a given site

Google’s Calculator

I use Google as a calculator too, by using standard symbols (+ – * / % ^)

Like: “2+10-5%2″ = 11, Google calculates in the manner which is done in programming languages.

You can also make it a scientific calculator using the below terms

sqrt,nth root ofx, sin, cos, arctan, tan…, ln, log, !

Numbers can be entered in hexadecimal, octal and binary base.

PS: There are many more things which you can do it Google but I have included which are useful.

Bing the latest offering from Microsoft is a great search engine, Its better than Google in various ways.

Bing has a better and more meaningful “Related Search”. It uses technology from Powerset (a search technology company Microsoft acquired) to display refined versions of your query down the left side of the page.
Bing also pop ups the text in the result page when you hover above the search result. Which will give the idea about to follow the result or not.
It has a Video Search in which one can refine the query by Length OR Screen size OR Resolution OR Source. I found this to be Good.
It’s Image search has all the features of Google as well as Introduced some more like layout, style, people.

And it knows that different kind of data is best represented in different format it will be hard to maintain this thing though as MS will depend on different sites to collect this data from.

Overall, The bing search is much more than expected and it may replace Google in Future as its just the beginning of Bing !.
