I think best way to get non-stemmed top terms is to index the field using a
fieldType that does not employes any stem filter. For example:
<fieldType name="non_stemmed_text" class="solr.TextField">
<analyzer class="org.apache.lucene.analysis.standard.StandardAnalyzer"/>
</fieldType>
By using copyField you can store two (or more) versions of a field. Stemmed and
non-stemmed.
Just a new field:
<field name="text" type="non_stemmed_text" indexed="true" stored="true" />
And a copy field:
<copyField source="your_original_field" dest="text" />
Schema Browser (Field: text) will give you top terms.
