i need it to find very quickly image edited with different software

As recommended to you before: use XMP properties instead of Exif properties where possible!

So use %xmp:tiff:software

To add it as a Custom Field:

Hi Hert
yes i get it , i use always Xmp properties
but in this case software is under tiff , it's a file format (like jpg or psd ) isn't it ?
thanks

Tiff is a file format but also a tag system (the t stands for Tagged). The software tag is defined in XMP standard as part of the tiff schema.

Hert,
I'm curious why use xmp vs exif?

In the past I've used exif which was a pain in the neck to edit so I stopped doing it. xmp seems much easier with not having to use special software to edit exif. As I recall some programs such as Capture One(?) wrote their name into exif and some don't (ON1).

I have found one oddity perhaps you can explain. I have some photos taken with Sony A7iii and the tiff:software custom field I just added shows Software: ILCE-7M3 v3.10. Because Sony writes to that xmp field thinking it's software too?

edit: Just noticed that Sony RX100 does the same thing.

Performance. PSU is XMP driven.
%exif is read from the physical file (meaning the file needs to be opened, the metadata read before the value can be displayed)
%xmp is read from the database

The camera write its software version (firmware is the software of a camera) in the software tag. That is perfectly fine.

Thank you for that information.
