Search options for "Full text" and "File name" are preserved only for that search
With no way to have the setting permanent. This kinda defeats the point as I don't expect people to be changing the option they prefer every time.
Also, it goes against the latest efforts avoiding temporary settings in the views and permanent settings in the preferences dialog, which was causing reports with confused users. In the last years we have moved all settings to permanent, and would be useful to rethink this one too.
