Don't Block Data Box Search Dialogue when Downloading Many Results
Problem:
Open send dialogue and search for a data box. Use full-text search. E.g. in production environment search for 'Brno'. This will produce over 40 thousands results. Downloading takes too long.
Proposed Solution:
Downloading should run on background and it shouldn't block the table view. Also a filter field should be added to make searching in results little bit more convenient.
