The kind field is never assigned, so calls to kind.isQuery() or kind.isFragment() will fail. Assign kind = ClientSideRemoteFlowKind.Query when m == "search" and kind = ClientSideRemoteFlowKind.Fragment when m == "hash`.

LocationFlowSource() {
exists(ServiceReference service, string m, int n |
service.getName() = "$location" and
this = service.getAMethodCall(m) and
n = super.getNumArgument()
|
m = "search" and n < 2
m = "search" and n < 2 and kind.isQuery()
or
m = "hash" and n = 0
m = "hash" and n = 0 and kind.isFragment()
)
}

override string getSourceType() { result = "$location" }

override ClientSideRemoteFlowKind getKind() { result = kind }
}
