This should do it. I did some searches. That triggers indexing when 
there is none.

Apart from min and max java mem i didn't change any solr defaults. I'm 
using solr 8.0.0 and setup as described in the wiki.
I changed the provided schema from the wiki to support partial searches. 
The index grew quite a bit but it's working fine.

What changes did you make to support partial searches?

added the line <filter class="solr.NGramFilterFactory"
minGramSize="3"
maxGramSize="15" /> after <filter
class="solr.LowerCaseFilterFactory"/>
to the <analyzer type="index"> block of the schema.xml from the
wiki.
Then remove your existing index and managed-schema, restart solr and 
reindex.

This nearly doubled the index in size but it's worth it.
