> 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="any query", 
>                  field="some_text_field", 
>                  minDocFreq="5",   //optional default is 5 documents
>                  maxDocFreq=".3", // optional default is no more then 30% of the index (.3)
>                  minTermLength="4",  // optional default is 4
>                  limit="50")                // optional default is 20
> {code}
