Remove duplication of "No matches found" message

In case if data is fetched in chunks, not at once, "No matches found" message is shown as many times as we requested for it.
Lets say we have 15 items, and data is fetched 5 at a time. After all items are selected, "No matches found" message would be duplicated 3 times.
