RE: Collations are not working fine.

Nitin,

Can you post the full spellcheck response when you query:

q=gram_ci:"gone wthh thes wint"&wt=json&indent=true&shards.qt=/spell

Hi James Dyer,
                          I did the same as you told me. Used
WordBreakSolrSpellChecker instead of shingles. But still collations are not
coming or working.
For instance, I tried to get collation of "gone with the wind" by searching
"gone wthh thes wint" on field=gram_ci but didn't succeed. Even, I am
getting the suggestions of wtth as *with*, thes as *the*, wint as *wind*.
Also I have documents which contains "gone with the wind" having 167 times
in the documents. I don't know that I am missing something or not.
Please check my below solr configuration:

wint"&wt=json&indent=true&shards.qt=/spell
