Here is the field type configuration of ctype:
<field name="ctype" type="integer" indexed="true" stored="true"
omitNorms="true" />
In solrconfig.xml, this is how I am enabling field collapsing:
<searchComponent name="query"
class="org.apache.solr.handler.component.CollapseComponent"/>
Apart from this, I made no changes in solrconfig.xml for field collapse. I
am currently not using the field collapse cache.
I have applied the patch on the Solr 1.4 build. I am not using the latest
solr nightly build. Can that cause any problem?
