The Science Of Searching
If you need to find something on the internet, you may use a ‘search engine’ such as Google or Yahoo. This kind of website gathers information about other websites into a big database for you to search. So how can you easily find what you are looking for, instead of getting millions of irrelevant search results? Here are some tricks that will have an immediate impact on your searching success.
Note: The information provided will work for nearly all major search engines. For specific techniques, look for a ‘search tips’ or a ‘help’ link on that particular search engine page.
1. Specifics Use words that describe exactly what you are looking for.
For example, the word
food will produce 215 million results!
free Italian cooking recipes will return 1.7 million results, whilst
free Italian desert cooking recipes narrows it down to 58,500.
Try to use words that explain what you are looking for in as much detail as possible.
2. Not helpful at all Most search engines will exclude ‘common words’ from your search, e.g. the, a, to, it etc. These words appear so often that they are not useful in narrowing down your results. The engine will ignore them or, if it supports this feature, it will process them as a ‘natural language’ search.
3. … What is natural language? Some search engines let you enter your search in question format, the same way you’d phrase it if you were asking a friend. For example: “How do I make tiramisu?”
Ask Jeeves (http://www.askjeeves.com) supports this ‘natural language’ searching.
4. Plus and minus aren’t just for numbers anymore
When searching the internet, (+) means ‘and’ and (-) means ‘not’. These two little symbols are extremely skillful at refining your results.
Brad Pitt appearances will return 841,100 results, whilst
+Brad +Pitt +appearances finds all three words on the same page in 291,100 results.
Use – to exclude words from your search, for example:
CSI returns 4.8 million results, whilst
CSI –Miami returns 4.1 million results (and doesn’t include information on the Miami version of this TV show).
5. It’s all in how you phrase it
Quotation marks “ ” are used to search for the exact phrase you’ve entered, in the exact order that you enter it (i.e. all the words together). This can help produce a better result than (+), as (+) will find all the words on that page, no matter how close they appear to one another. For example:
star trek at 7.9 million results could contain articles on astronomy whilst
“star trek” at 7.4 million results is more likely to give just results mentioning the TV series/movies.
6. And when you put it all together …
You can use a combination of the tips above, for example:
“star trek” –“next generation” - voyager +”deep space nine”

The home PC will be extinct within 5 years
Having tried out some of these new web based office tools, such as the Google ones and Webex Office I am pretty sure that within the next 5 years people will stop buying PC's and buying software to install on those PC's and then subsequently worrying about patches and upgrades.
People will pay about $25 a month to subscribe to a remote service that will take care of word processing, spreadsheet, accounts, photo applications, music etc. That will be delivered on demand over a 40 MB internet link.
The PC will be replaced by a small slab about the size of a VCR cartridge. This will contain a local processor and a small disk for temporay local storage. It will consume about 5 watts in operation and have a 10 second start up time from cold. The Wyse thin client boxes already approach this type of thing. There will still be local LCD (or equivalent) screen and a full sized key board, though voice recognition will increase.
The operating system will be irrelevant on the local Personal Unit (PU) either Microsoft or LINUX. The PU will be virus prooof with the local operating system held on a read only card. Complex functionality will come from the central service provider.
Forget about login and account passwords, this will be dealt with by a combination of finger print scan and a SIM sized smart card. Your mobile phone will connect via your house Wireless Router, but also link into your PU for Skype type of phone calls.
The bad news for Microsoft (unless they change) is that public will no longer have the continual round of having to upgrade software (& PC) every three years.
