1) add video with "test" text in description
2) edit video in dashboard (edit stream item), delete "test", save it
3) try to search "test"
Result: System still would display this video.
Excepted result: System should not display this video because there is no "test" text at the moment.
It works normal if edit video exactly (not stream item) on video page. I suppose stream item (with video) editing should work the same way.
