Mark Miller commented on SOLR-2725:
-----------------------------------
Just as an FYI, setExpungeDeletesPctAllowed is now setReclaimDeletesWeight.
In any case, setters are already supported via the general solrconfig class
loading mechanism, so I don't think there is anything to do here.

<double name="reclaimDeletesWeight">0</double>

> TieredMergePolicy and expungeDeletes behaviour
> ----------------------------------------------
>
> Key: SOLR-2725
> URL: https://issues.apache.org/jira/browse/SOLR-2725
> Project: Solr
> Issue Type: Bug
> Affects Versions: 3.3, 3.4, 3.5, 3.6
> Reporter: Martijn van Groningen
>
> During executing a commit with expungeDeletes I noticed there were still a
> lot of segments left.
> However there were still ~30 segments left with deletes after the commit
> finished.
> After looking in SolrIndexConfig class I noticed that
> TieredMergePolicy#setExpungeDeletesPctAllowed isn't invoked.
> I think the following statements in SolrIndexConfig#buildMergePolicy method
> will purge all deletes:
> {code}
> tieredMergePolicy.setExpungeDeletesPctAllowed(0);
> {code}
> This also reflects the behavior of Solr 3.1 / 3.2
> After some discussion on IRC setting expungeDeletesPctAllowed always to zero
> isn't best for performance:
> http://colabti.org/irclogger/irclogger_log/lucene-dev?date=2011-08-20#l120
> I think we should add an option to solrconfig.xml that allows users to set
> this option to whatever value is best for them:
> {code:xml}
> <expungeDeletesPctAllowed>0</expungeDeletesPctAllowed>
> {code}
> Also having a expungeDeletesPctAllowed per commit command would be great:
> {code:xml}
> <commit waitFlush="false" waitSearcher="false" expungeDeletes="true"
> expungeDeletesPctAllowed="0"/>
> {code}
