No cluster results is displayed next to the search results.
Is this because I turned clustering on after running the fetch and the
indexing?

<description>Regular expression naming plugin directory names to
include. Any plugin not matching this expression is excluded.
In any case you need at least include the nutch-extensionpoints plugin. By
default Nutch includes crawling just HTML and plain text via HTTP,
and basic indexing and search plugins.
