Description

From what I understand solr execute queries to determine if the suggest return results.
https://cwiki.apache.org/confluence/display/solr/Spell+Checking#SpellChecking-Thespellcheck.collateParameter

The spellcheck.collate parameter only returns collations that are guaranteed to result in hits if re-queried, even when applying original fq parameters.
it would be great if solr will order the collations by numFound, so the collations with more results appear first.

i.e:
spellcheck.q = prditive analytiycs
spellcheck.maxCollations = 5
spellcheck.count=0

response:

<lst name="spellcheck">
  <lst name="suggestions"/>
  <bool name="correctlySpelled">false</bool>
  <lst name="collations">
    <str name="collation">positive analytic</str>
    <str name="collation">positive analytics</str>
    <str name="collation">predictive analytics</str>
    <str name="collation">primitive analytics</str>
    <str name="collation">punitive analytic</str>
  </lst>
</lst>

Obviesly that "predictive analytics" have more results from "positive analytic".
