Nitin, My guess here is that your spellcheck field is a field that has stemming. This might be why you get a collation that return "wind" even though the user queried "wnd" and it does not get any suggestions. Perhaps "wnd" is stemmed the same as "wind" ? (Spellcheck usually works best if you "copyField" the query field to something that is tokenized but not heavily analyzed, and use the copy as the spellcheck dictionary.)
The other problem might be because "wind" is in the index but you are not using "spellcheck.alternativeTermCount". If you set this to the same value as "spellcheck.count", then it will give suggestions even when words exist in the index. By "hits", it means if you replaced the "q" parameter on the original query but left everything else the same (filters, etc), this is how many results you would get. If you need more help, please include in your message the pertinent sections of solrconfig.xml, schema.xml and also the full query url you are using and the full spellcheck response.

I am working on spell checking in Solr. I have implemented Suggestions and collations in my spell checker component. Most of the time collations work fine but in few case it fails. *Working*: I tried query:*gone wthh thes wnd*: In this "wnd" doesn't give suggestion "wind" but collation is coming right = "gone with the wind", hits = 117 *Not working:* But when I tried query: *gone wthh thes wint*: In this "wint" does give suggestion "wind" but collation is not coming right. Instead of gone with the wind it gives gone with the west, hits = 1. And I want to also know what is *hits* in collations.
