clean=true deletes entire solr index (delete by query *:*) before import
operation. By default it is true in full-import, false in delta-import.
&optimize=true by default in delta-import.
So just solr/dataimport?command=delta-import should do optimize.
you should see something like:
<str name="Optimized">2010-03-30 10:13:14</str>
May be your delta-import is not updating/adding/deleting any documents.
