Instead of “segment” now I’m using the “search” function to make a more specific selection.
All works fine BUT if I use the “Total” count line, the numbers are all wrong, because Matomo still consider all results and not the the only ones “selected” by search function.
Segments in Matomo are visit based, so a segment will return any visits that match your criteria but this would also include any actions that occurred within those returned visits. These actions could be other page views, events, goals etc. This will be why you see other PageURLs in your report with the segment loaded.
In regards to the ‘Totals’ row, the total is not dynamic unfortunately. The total will be based on all rows in the report. When searching the report for a certain row, the total row would still be based on the entire report.
