This seems to be a serious bug - it can be easily reproduced: I've created a bookmark with a specific sorting:
But as soon as I refine the search with an additional search term, the sorting changes:
This is annoying, as it goes against the usability of bookmarks. Please fix this bug, so that when I REFINE the search the sorting doesn't get lost. Thank you!
Everything 1.3 doesn't index size or dates, keeping the sort for these types would be extremely inefficient.
To always keep the current sort in Everything 1.3, enable always_keep_sort.
If you would like to keep the sort for these types, please try the Everything 1.4 beta as it will index this information.
You will also need to enable fast sort for size and dates in Everything from Tools -> Options -> Indexes (as skribb mentions above).
