XnView Software

I want to organize quite a lot pictures using XnViewMP.
I used short descriptions using both embedded comments and annotations.
The embedded comments are great to used indexed search of the methadata using DocFetcher, it's a really fast way to find pictures. But the program doesn't show thumbnails.
I can get fast results if I search nonrecursive inside one folder using quicksearch or the advanced search option.
To open all pictures recursive at the trunk of the tree to use quicksearch is a possibility, but to open all the pictures will need some time.
To search all the folders recursive using advanced search will also need a lot of time.
So I thought it would be wise to search not for comments but for annotations. Then the program has only to go through the description.ion files an not through all the pictures. A simple text-search through a few dozens of "text-files" should be simple and fast, shouldn't it?
An that is true if I use XnView (recursive search for annotations is a lot faster than the same search for comments). It is not true for XnViewXP. I tried it out.
Why is that so? Are there plans to change the algorithm for faster search of annotations? Or should i just uses good old XnView oder XnView and XnViewMP parallel for different tasks?

EDIT: I planed to change to XnViewMP because I think it is the more promising product in the future.

you search by annotations with Search dialog?

Yes, I open the search dialog with Ctrl+F, select "Recursive through subfolders" and add a condition for an annotion.

Thanks to your detailed description I can reproduce the problem.

Thanks for looking into the problem so fast.

This problem is supposed to be fixed in XnView MP 0.91. Please check and confirm the bug fix here.
