> The significantTerms Streaming Expression will emit a set of terms from a
> *text field* within a doc frequency range for a specific query. It will also
> score the terms based on how many times the terms appear in the result set,
> and how many times the terms appear in the corpus, and return the top N terms
> based on this significance score.
> Syntax:
> {code}
> significantTerms(collection,
> q="abc",
> field="some_text_field",
> minDocFreq="x",
> maxDocFreq="y",
> limit="50")
> {code}
