dbPedia lookup: temporarily replace PrefixSearch with KeywordSearch, …

…but this is annoying.

Alas, the dbpedia lookup (completion) is still down , and the team (Magnus Knuth) did not provide a date for fixing .
I consider moving to Wikidata, but Wikidata does no do completion; however it is probably never down, and it IS internationalized .
