    For making search engines you have to make crawlers and for that just asp.net technology is not enough i will see very less use of database in the search engine crawlers

    well,the idea of a good search engine is not limited to just one technology like c#.it has to do with the design of a custom algorithm for efficient search.
    From my understanding,you.l have to create a robot or small app that will crawl the web,you'l then store the crawled information on disk or database depending on the kind of information you crawling......you.l then create a kind of index for those content youv crawled.it's that index that you.l implement your search on and users will get result real fast......i can break this down into a 3 step solution.
    Determine the kind of information to crawl online
    Determine the best way to store the crawled information
    Index the crawled content and implement a search for this crawled content.
    There is a library,Lucene.Net which is very good for indexing and search,you can google it to get more information about it.

    You want to make a complete search engine. So, first understand how so such search engine (google, bing, yahoo, grotal) work and why they differ from each other.
    Basically search engine can be divided into 3 major parts.
    1. Crawler - tool/ software/ web service OR anything that collects information.
    2. Database - storage where crawler store all data (could be any database or file system).
    3. Search algo - A program that understand your queries and fetch data from own database as a search result.

    Technology is not a limitation for creating a search engine. You can create a great search engine using ASP.Net MVC and Sql Server.
