  • I would start to determine what you search engine wants to find..
    and please don't say everything (like google) as you will never have enough server power for that if this is just a fun project.
  • making a search engine kind of requires knowing how to program.

    here is a good open source site search engine script that spiders the site.

    Take a look how it works:
