Update default tokenizer to "standard"

We formerly used also implicitly the standard tokenizer.
Using "whitespace" breaks some API call, e.g. "item?q="DE-5-4"
because it would'nt be tokenized.
So this fixes also an issue introduced silently introduced in #533
with commit b76c92a6f0b1817272e98a8ef22fc2b1676ba0f3.
