How to sift files with certain string in file name

[Makak007]

Hello,
my problem is as follows:
Let´s say i have a folder with many jpg files named:
1filename (1).jpg
1filename (2).jpg
1filename (3).jpg
1filename (4).jpg
2filename (1).jpg
2filename (2).jpg
2filename (3).jpg
2filename (4).jpg
3filename (1).jpg
3filename (2).jpg
3filename (3).jpg
etc...

is there an easy way to sift all files with " (1)" in its name? In this case files:
1filename (1).jpg
2filename (1).jpg
3filename (1).jpg
etc...

Anyone can advice me how to achieve that? Many thanks in advance for your kind help.

Good question

With Everything enabled doesn't work.

Are you sure? I just tested with [ ] 'Everything' checked, it is work!

For me - doesn't. May be related to my Everything settings?

PS
Got it! Works fine when option Allow round bracket grouping is disabled

Works fine when option Allow round bracket grouping is disabled

Which seems to be the default.
