[jira] [Updated] (SPARK-20795) Maximum document frequency for IDF

     [ https://issues.apache.org/jira/browse/SPARK-20795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Turan Gojayev updated SPARK-20795:
----------------------------------
    Description: In current implementation of IDF there is no way for setting maximum number of documents for filtering the terms. I assume that the functionality is the same for minimum document frequency, and was wondering, if there is a special reason for not having maxDocFreq parameter and filtering.
