I just started using the StackOverflow 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.
