Google API returning different results than website
This google page has what you are looking for https://support.google.com/customsearch/answer/70392?hl=en
your results are unlikely to match those returned by Google Web Search, for several reasons:
- Even if a custom search engine is configured to search the entire web, it’s designed to emphasize results from your own sites.
- Your custom search engine doesn’t include Google Web Search features such as Oneboxes, real-time results, universal search, social feaures, or personalized results.
- If your custom search engine includes more than ten sites, the results may be from a subset of our index and may differ from the results of a 'site:' search on Google.com.
