1.9.0 - AND/OR quick filters work differently

[moropus]

XnView: MP 1.8.8-1.9.0 64 bit
OS: Windows 64bit

I use quick filters to sort my photos a lot.
I noticed that adding + (and) and | (or) to filters works differently and inconsistently:
* no partial match with +
* no mixing different search sources like category and name

To reproduce:
1. Click Quick filter menu, select Search in Categories
2. Add multiple categories, eg "Cats" and "Dogs"
3. Create multiple images, eg image1.png, image2.jpg, image3.jpg
4. Assign categories:
- Cats -> image1.png
- Dogs -> image2.jpg
- Cats, Dogs -> image3.jpg

5. Search "cat+dog" in quick filter
Actual behaviour (bug): Nothing is found
Expected behaviour: image3.jpg is found

When I search "cat" or "cat|dog" (part of the category) I've got all the results I expect, but + filter doesn't respect partial match.

6. Search "cats+png"
Actual behaviour (bug): Nothing is found
Expected behaviour: image1.png is found

When I search "png" or "cats|png" (category with extension) I've got all the results I expect, but + filter doesn't work with different search sources.

I've tried and it works correctly. 'Categories (catalog)' is enabled?

Screenshots:
1. 'Categories' option is enabled.
2. I search 'кот' and find jpg with two categories
3. I search 'кот+jpg' (category and format) and find nothing
4. I search 'кот+пес' (two categories) and find nothing

Partially fixed (1.9.1 x64, Windows 10 x64).
Filter with two categories 'кот+пес' now works as intended.
Filter category and format 'кот+jpg' still finds nothing.

jpg is not in categories

[moropus]

jpg is not in categories

It surely is not.
But I find it extremely useful to search by multiple properties at the same time, since 'кот|jpg' works with category and format/name.
Eg I usually search for images with specific subject (category) which I have already edited (format jpg, not raw).

you can add 'thumbnail labels'

Checked, and it doesn't work.

ok im wrong, currently + can only be used on categories

what kind of search is it ?

maybe add/use 'simple search' by default (with simple wildcards * ? )
Browser - quick filter - improve search settings
