How do I edit my search to remove specific substrings from URI values in my results in statistics tab?

I wrote the query which gives below result in statistics tab URI Count HTTPS://XXXXXXXX//AAAA.aspx%3FUIC=GuidID=8090443C5BA5ED33%26_SecEntityType=1%26BID=71E160E1E55478D5 1 HTTPS://XXXXXXXX/CCCCC.aspx?UIC=GuidID%3d952932873084A530%26_SecEntityType%3d1&BID=9B387A4FD720BD78 1 HTTPS://XXXXXXXX//AAAA.aspx 2 HTTPS://XXXXXXXX/CCCCC.aspx 2 However i was looking a way to remove the data after .aspx and have the count included in statistics. I expecting the statistics to look like URI Count HTTPS://XXXXXXXX//AAAA.aspx 3 HTTPS://XXXXXXXX/CCCCC.aspx 3
