Now after pressing "Search" in TM Maintenance we send the first request with limit of 20 segments and after it is done we send a request for reading the total amount. After the user scrolls to the end of the grid we then send requests for reading segments one-by-one in bunches of 20. This leads that the first request till the result appears after a longer time for big TMS.

This behaviour needs to be changed the following way:
After "Search" is pressed need to read first bunch of segments not in one request, but using the same approach as when scrolled to the end of the page - in 20 requests on-by-one. Regarding "read amount" - it should be sent after the first 20 is read.
