## Class MoreIndexingFilter

- java.lang.Object
- - org.apache.nutch.indexer.more.MoreIndexingFilter

- All Implemented Interfaces:
    Configurable, IndexingFilter, Pluggable

      public class MoreIndexingFilter
      extends Object
      implements IndexingFilter

  Add (or reset) a few metaData properties as respective fields (if they are available), so that they can be accurately used within the search index. 'lastModifed' is indexed to support query by date, 'contentLength' obtains content length from the HTTP header, 'type' field is indexed to support query by type and finally the 'title' field is an attempt to reset the title if a content-disposition hint exists. The logic is that such a presence is indicative that the content provider wants the filename therein to be used as the title. Still need to make content-length searchable!
