Finder windows with searches not shown at finder icon window list

Hi,

I do not know if it is a bug or feature...

Running Catalina 10.15.4 in an iMac Retina

If I have several finder windows (with file listings) open, they all show up when I

right click the Finder dock icon in the top open window list.

As it should be.

But if I make a search in one finder windows - either on a local drive or a remote,

mounted volume - that file windows is deleted from that open windows list.

After I close the search, that file window reappears in the open window list.

Is that as it should be?

regards,

Claus Bitten
