I guess that this functionnality isn't implemented yet. I'll begin by an example to explain what I'm requesting:
I have a lucene query that get articles satisfying a certain query. With this same command, I'm getting at the same time suggestions if this query doesnt return any article (so far, nothing unusual).
The frequency (count) associated with these suggestions is relative to all index (it counts all occurences of the suggestion in the whole index). What I want is that it counts only suggestion occurences satisfying current lucene query.
P.S: I'm using solr's spellcheck component (solr.DirectSolrSpellChecker).
