Well firstly I’d say go and find a computing science / software engineering course/institution which features at least one class on information retrieval, distributed systems and discrete math (if you need it) and get an A+ in them, then find an academic willing to let you prototype your industry-scaled search engine as a student project (good luck, you’ll need it)

Secondly, you’ll need a fair amount of money to pay for:

– lots of clustered computers (to construct, store and retrieve indices at a decent rate)
– lots of internet bandwidth (to poke about the web at a half-decent rate), or some other way of getting the required data regarding web structure and content.

As for a web spider, write your own – it’s the easiest part of such an endeavour and if you can’t do that, you’re biting off far more than you can chew in attempting a fully-featured google/yahoo scale search engine which can compete (in terms of performance and appropriate results rate) with yahoo or google.

wouldn’t that cost alot?

buy yahoo and microsoft..
or call bill gates and ask him if he want 2 sell with lower price..
search engine is a big structure..you need a team..huge team..to make it different..
it only be powered by google or yahoo..next ten years i dont know what

How can you create your own search engine like Yahoo! or Google?

The world wide web is owned by a private company in Virginia, I think it’s in Langley Virginia.

You have to have the electronic equipment and pay the company an annual fee to register, and then you are licensed to operate with your chosen name provided no other operator has that name.

When you do, please create a BETTER Answers than the yahoos at Yahoo have created! I already use Mail.com for my electronic messages because MSN, Hurtmail and Yahoo are so horrible! Please hurry!

Your too late. It’s been done.

buy a spider or crawler ….or hire a development team
