Joel Bernstein updated SOLR-10156:
----------------------------------
Description:
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}
