Sometimes, searching services with port numbers won't work for an exact match. But the same will show the result for the port range configured services if the port number is in the range.
The issue will occur when we upgrade the Junos Space Security Director to the 24.1 version.
In example, while looking for service "tcp_8443", you can't find it by writing "8443" or "tcp_84" but you have to put the whole service name as is to the search bar. Same goes to other services like "53" can't find any dns service objects.
The is a BUG in SD 24.1
The BUG reported in the PR 1858790 and it will be fixed in SD 24.1R3HPv3
