Fix deleted documents search

When we have trashed documents and we do a search, it's only working for the first time, if we try to filter after the first search, nothing happens

How to reproduce:

• create/upload 2 files with different sizes - ex:
  • 1 with the size Less than 100 KB
  • 1 with the size Between 100 KB and 1 MB
• go to the workspace/folder of those files and delete them
• go to trash view
• you can see both files you deleted
• in the Size filter check the Between 100 KB and 1 MB checkbox
  • you only see the correct file - search ok

• uncheck the Between 100 KB and 1 MB checkbox
  • you still have the same file in the search - bug and the trash search filters stop to work
