The following page has been changed by DominiqueDeMunck:

------------------------------------------------------------------------------
  
  See [http://jakarta.apache.org/lucene/docs/index.html the Lucene documentation] for explanations
of what they mean.
  
+ === The optimize-frequency attribute (since version 2.2) ===
+ 
+ Determines how often the lucene index will be optimized. When you have 1000's of documents,
optimizing the index
+ can become quite slow (eg. 7 seconds for 9000 small docs, P4).
+ 
+ 
+   * 1: always optimize (default)
+   * 0: never optimize
+   * x: update every x times. You can use any number, it is a random generator which will
determine to optimize or not. 
+ 
+ You can eg. create a pipe without optimizing, which is used to index you're document everytime
when it's modified. 
+ You can then create another pipe which will optimize, which is called manually. 
+ For more info see the Lucene FAQ , What is index optimization and when should I use it?

  === The directory attribute ===

{{{work}}} directory.
