I can't find any site that teach me or give me some information about how to create a search engine. I'd like to create something like this tenshichan dot com. This site allows you to search for images in some particular sites. Could you please help me to create something like this (a search engine for images) or link me some sites that teach how do it, I'd like to implement this feature in my website, so that I can offer a useful features for my visitors . Thanks in advance and sorry for my bad English, but it isn't my native language.
You need what's called a "meta search engine". THere are free ones, or you can buy the in-out search engine To make your own without using the "meta search engine" solutions will require software and dedicated computers, running all the time spidering pages
