You need to 'add url' to Google, Bing and Yahoo.
If you use Google Webmaster Tools, you will be able to submit a Sitemap, which will tell Google how many pages of your site need indexing. You can also tell Google how often to crawl your site for updates, as well as many other useful tools for you to check your site's performance.
If you are new to all of this, then you should also register your site with Google Analytics - another important tool for improving site maintenance.
But remember - changes to your site and indexing usually takes 2 - 4 weeks - so be patient, it will happen eventually
