Subject [jira] [Commented] (LUCENE-4813) Allow DirectSpellchecker to use totalTermFrequency rather than docFrequency
Date Fri, 08 Mar 2013 13:10:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4813?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597101#comment-13597101
] 

Robert Muir commented on LUCENE-4813:
-------------------------------------

Can we do without the FieldStatistics/DocFreqStatistics/etc and just change 'freq' to long?

> we have a bunch of new statistics in on our term dictionaries that we should make use
of where it makes sense. For DirectSpellChecker totalTermFreq and sumTotalTermFreq might be
better suited for spell correction on top of a fulltext index than docFreq and maxDoc
