Creating a crawler for a particular website

[babbupandey]

Hello everyone,

I am trying to develop a crawler for a website (nextag.com), the idea is to take the search query and pass it on to nextag and then get the results of the website in an array.
I am not sure even on how to get started, I tried reading tutorials but they were not much of a help for this particular problem. Any help will be greatly appreciated.

Thanks

Basically are you want to develop a search engine for your web site, is it?

[babbupandey]

In a manner, yes.
The website has its own search feature, however, I want that the user should pass the query through the program I have developed. I should be able to get total number of results and page-wise results in an array.
So suppose user passes the parameter "mobile phone, 2" then I should be able to list the results given by NexTag.com for "mobile phone" on page number #2 of the results page.

How about the following resources. I've customize few of them used several times. May those things not exactly what you want, but it's possible to modified them.
