"Search" - some questions

[Peter2]

I have some question for the "search"-dialogue:

xnviewmp_search.png

a) The radio-buttons "Match all of ... / Match any of .." are related to the ..
1) conditions right next to them: "case .. / Recurse ../ .."
2) conditions below?
If it is 2), I suggest to modify the arrangement and move the radio-buttons closer (or to the bottom) of the "conditions area"

b) What is "All fields"?
1) "all following metadata fields" or
2) all definitions everywhere: dates, comments, format, ..
If it is 2), it should be changed to "all metadata (fields)"

c) Difference between criteria "is any of" and "contains" - I'm not sure how it works
Let's assume we have metadatas "very_big / very_small / ugly".
- Contains "y": 3 results
- Contains "ver": 2 results
- Contains "mug": 0 results
- is any of "ver": 0 results
- is any of "very_big, ugly": 2 results
Is that correct?

Categories, rating, color label, file size, date, format, IPTC, EXIF

c) Difference between criteria "is any of" and "contains" - I'm not sure how it works

'is any of' check for word separated by ,
