solr reindexing issue for EdgeNgramFilter

Question

I have created a rails application with Solr search(sunspot gem). It is working good in my local system but when I deployed to production server, I faced a serious problem.

When I run the re-indexing command RAILS_ENV=development bundle exec rake sunspot:solr:start, it's not showing any error. It successfully re-index the data. It also showing at the admin side that all data is re-indexed properly.

But when I search something, it's not giving the proper result. And when I execute the same search query in my local machine it gave the proper relevant result.

There is also weird behavior in server: when I did manually changes in the file and did Solr start stop without re-index. Then it will give proper result.

I use the following command for re-indexing the solr RAILS_ENV=development bundle exec rake sunspot:solr:reindex

Here is my schema.xml file:
