For comparison purposes I need to merge segments of a Solr core to only one segment. Changing the solrconfig by playing with following lines

<mergePolicyFactory class="org.apache.solr.index.TieredMergePolicyFactory">
  <int name="maxMergeAtOnce">10</int>
  <int name="segmentsPerTier">10</int>
</mergePolicyFactory>

won't take any effect rather than bad exceptions.

    Remember that any mergePolicy definition has to live inside `indexConfig`. And call optimize on the index to force a possible merge. – MatsLindh Jun 17 '16 at 20:29

Thanks for your answers, executing following command will force merge to an amount of segments of your choosing: "http://FOO:8983/solr/BAR/update?optimize=true&maxSegments=1&waitFlush=false"
