Bridge - Filter Out Option

[Rinathee]

Apologies if this has been asked before but I cannot seem to find a post for my specific query.

Lets say I've got a folder of animal pictures and I've tagged them based on what animal(s) are present in the picture. Is there any way for me to search for all files that have been tagged as 'Cat' and filter out any files that have any other tags that are not 'Cat'? So I don't want any files that have keywords Dog or Bird to show up in the browser. 

I'm aware that there is a workaround in advanced search by adding a search criteria Keyword contains [other possible tag], but when there's a large variety of possible tags that would be cumbersome.

There is the Filter Panel which can filter on keywords but it is a positive filter so will find all "Cat" keyworded images but doesn't cater for "Cat and not Dog". The Find function (Edit>Find or Ctrl+F) can do this however because you can enter multiple criteria including negative criteria. For example enter two criteria "Keywords>equals>Cat" and "Keywords>does not equal>Dog". Check the box which applies both criteria.

You have to specify the excluded terms. There is no way to search for ONLY one keyword.
