hi
now i implemented search and it works but another question rises up:
I tried to filter on all fields with option "contain".
You may try it on plunker:

Try it with single charctes "d", "f", "g", no filterresult, despite the fact that there are plenty of fields containig these charactes.
If searching for "de", or "fe", result is correct.
