Class LineDocSource

java.lang.Object
  org.apache.lucene.benchmark.byTask.feeds.ContentSource
      org.apache.lucene.benchmark.byTask.feeds.LineDocSource

public class LineDocSource
extends ContentSource

A ContentSource reading one line at a time as a Document from a single file. This saves IO cost (over DirContentSource) of recursing through a directory and opening a new file for every document.
The expected format of each line is (arguments are separated by <TAB>): title, date, body. If a line is read in a different format, a RuntimeException will be thrown. In general, you should use this content source for files that were created with WriteLineDocTask.

Config properties:

• docs.file=<path to the file>
• content.source.encoding - default to UTF-8.
