Hi
1. About the search module, seems there is something with css. Could you please submit a support ticket sending us super admin account of your site so that I can ask my template developer to look at it and get it sorted?
2. About the "display options and sort order", yes, it is possible. Go to EDocman -> Configuration, look at Themes tab, find the config option "Show sort options", set it to No
After that, it will work as expected
