Solr 4.7.2 mergeFactor

Hi All,

I am using solr 4.7.2 is there a bug wrt merging the segments down ? 

I recently added the following to my solrConfig.xml

  <indexConfig>
    <useCompoundFile>false</useCompoundFile>
    <ramBufferSizeMB>100</ramBufferSizeMB>
    <maxBufferedDocs>1000</maxBufferedDocs>
    <mergeFactor>5</mergeFactor>
  </indexConfig>


But I do not see any merging of the segments happening. I saw some other people have 
the same issue but there wasn’t much info. except one suggesting to use 
<mergePolicy class="org.apache.lucene.index.TieredMergePolicy">
      <int name="maxMergeAtOnce">5</int>
      <int name="segmentsPerTier">5</int>
    </mergePolicy>
<mergeScheduler class="org.apache.lucene.index.ConcurrentMergeScheduler”/>

instead of mergeFactor.

Thanks,
Summer

Thread Hijacking on Mailing Lists

When starting a new discussion on a mailing list, please do not reply to 
an existing message, instead start a fresh email.  Even if you change the 
subject line of your email, other mail headers still track which thread 
you replied to and your question is "hidden" in that thread and gets less 
attention.   It makes following discussions in the mailing list archives 
particularly difficult.
