Erick,
We actaully have a working version of Solr 4.6 Spellchecker, the
configuration details are as mentioned below:
*Solr 4.6 - schema.xml*
<field name="suggest" type="text_suggest" indexed="true" stored="false"
multiValued="true" />

Now, we are migrating to Solr 5.1 & have the following configuration
details:

</fieldType>

<int name="endOffset">2</int>
<arr name="suggestion">
*<str>we</str>
<str>who</str>*
</arr>
</lst>
</lst>
</lst>
</response>
Both the Solr versions have same data & spellcheck index is also built.
I want to get the same results for Spellchecker in Solr 5.1 as I am getting
in 4.6, but I am not able to get it.
Can you please suggest an appropriate fix?
Is there some problem in my Solr 5.1 configuration?
Regards,
Sachin Vyas.
