Subject [jira] Commented: (SOLR-2118) IndexReaderFactory.setTermIndexInterval is misleading and confusing
Date Sun, 12 Sep 2010 13:47:32 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12908465#action_12908465
] 

Mark Miller commented on SOLR-2118:
-----------------------------------

Right, I get you now - I thought that was a typo in your examples.

I didn't realize that this triggers a method that someone put on the reader factory rather
than trying to work with the indexreader.

So this is more a bug than an improvement.

> I feel the IR parameter should be *setTermIndexDivisor* or similar instead:
