Please evaluate the possibility that the search engine indexes sighted revisions only. This is to prevent vandalism to be displayed at a prominent place.
Background: After the elections in Israel a few days ago the articles about the candidates like Benjamin Netanjahu are both interesting for readers and target to vandals.
This article was vandalised on the 12th february at 04:29 CET in a horrible way (think of Hitler and the Shoah and you'll guess what i mean). The vandalism was undone about 15 minutes later and the revision was deleted in the meantime. Unfortunately the daily search-indexing of de-wp took place during that quarter of an hour, so the vandalism showed up every time someone searched for Netanjahu. When i was told about this i asked at #wikimedia-tech to manually re-index de-wp.
Every article on de-wp has a sighted revision by now, so this solution would prevent offenses like the one described above.
