I just started using the Stack Overflow API. I want to collect all questions related to a specific keyword.

My code iterates over all result pages by increasing the `&page=N` parameter while `'has_more'` is `true`.  However, I noticed a discrepancy in results between the result I find when I search for the term on the site and when using the API.
For example, when I search for GDPR on stackoverflow.com I get 1,449 results. When I use the API I get 855 results. 


This is my filter: `&filter=!-PM0x_wtQ*dB)nch99.Yykxk*OOLMzj.H`

I still have enough quota.
