search engines

[benf]

I've been trying to find what a search engine is programmed in and how difficult it is to create. Is it possible to create a specialist engine that can distinguish and search through only certain types of websites?

What are the spiders programmed in? Can you do alot of this in PHP or would you need to compile this sort of thing in java or c++?

thanks.

well according to me after doing few research into search engine making and their working, PHP is the preferred language for ease of handling...

You can always try the Google SE code they provide for webmasters to integrate Google Search intp their website.

This will help you...

I think he is looking to actually code his own engine...

PHP and Mysql would do the job...

This definetly can be done. The programming to crawl and index certain dtat based on variables you set is the easy part, it's where you put all the data when your done and how fast you can process that data that will be the most difficult...

So would you specify variables such as within certain HTML tags or keywords?

Would you say that most search engines index various data in a few separate databases or databases with sub menus and so on.

Do you know any websites where i can read up on the subject of search engine making / programming.

Do you think this sort of programming is very difficult?

thanks for the help.
