If you're seeing more results than you expect, make sure you've specified that you want to search only the sites you provide, not the entire web, in your Custom Search Engine control panel.
If you are not seeing a particular result that you expect:
- Make sure that you have included the result or the pattern matching the result in your Custom Search Engine. Beware of spelling mistakes!
- Make sure the page you expect to see is in the Google index. A simple way of checking is to do a search on Google with the site: operator along with a few words on that page as a search query. For more information about how Google crawls and indexes pages, all of our resources for site owners can be found at Google's Webmaster Central.
