> The termVectors Stream Evaluator returns tf-idf word vectors for a text field
> in a list of tuples.
> Syntax:
> {code}
> let(a=select(search(...), analyze(a, body) as terms),
> b=termVectors(a, minDocFreq=".00", maxDocFreq="1.0"))
> {code}
> The code above performs a search then uses the *select* stream and *analyze*
> evaluator to attach a list of terms to each document.
