Translation:The search is available in German.
You can - as far as grammar is concerned - change the German word order in that way: "Die Suche auf Deutsch ist verfügbar."
...but it sounds unnatural both in German and in English to me (normally you'd just say, "Die deutsche Suche ist verfügbar"), unless the situation is that you work for Google, and Google is available in many languages, and "the search in German" stopped working. So, "the search in German" is what it's about. Then, if the German Google works again, you could say, "Die Suche auf Deutsch ist wieder verfügbar."
Similarly, if you're at a library: "Haben Sie 'Harry Potter' auf Deutsch?" - "Ja, 'Harry Potter' auf Deutsch ist verfügbar." (= you can borrow it today) - it's not about whether there exists a version of "Harry Potter" in German, it's a question about an actual "German 'Harry Potter' book".
