On August 21 data source for search volume will be changed

As of August 21, we will obtain the search volume for the Search terms endpoint from another data source. In the new data source, traffic is measured and filtered out where necessary in a slightly different way compared to the old data source. From August 21, the change may cause search volume to differ slightly from before. As is the case now, we will still support four years of search data history. Historical data will not be adjusted; all data before August 21 remains as-is.
