Hello Dong,
Thank you for reaching out. Please find my response to your queries below.
search_term_view == aw_searchqueryperformancereport ? Yes, the equivalent for Search Query Performance Report in Google Ads API is using the search_term_view resource. You might find this migration guide useful for the equivalent of Adwords reports in Google Ads API.
The data from search_term_view is inconsistent with the number of results seen on Google Ads: Could you please share the client customer id for me to investigate this inconsistency further? Please use Reply privately to author option while sharing the details.
Regards,
Nikisha Patel, Google Ads API Team
