Discussion of bugs and problems found in Altap Salamander. In your reports, please be as descriptive as possible, and report one incident per report. Do not post crash reports here, send us the generated bug report by email instead, please.
I wanted to find files in subdirectories only, excluding files in the current dir.
So I did a search with Search subdirectories ticked. Then I did a Refine - Subtract from Found Items with the same search conditions but Search subdirectories unticked.
All found files and folders were removed. Why?
The Look in field (including Search subdirectories option) is ignored during Refine * Found Items commands. So in your case all items found in the first stage are "subtracted" during the second stage.
I don't think it is possible to do with Salamander, I'm sorry.
You can simply bypass this problem: in Find window in Found Items listview: select items from the first to the last on current path (watch Path column) and use Files/Hide command (Ctrl+H). Or you can sort items by Path (click on column header) and select & hide files from any other directory.
