Sorry for sending this first to the wrong person. It was actually supposed  
for the mailing list :)

To enable keyword substitution on all Java files I would do something like  
this from the command line:

find . -name "*.java" | xargs svn propset svn:keywords "Id"

This should fix up all the java files.
If you are using some sort of IDE (subclipse, smartsvn, ...) you should be  
able to select somehow multiple files and then set the svn:keywords  
property.

What exactly do you have in mind? Some sort of Lucene Management API which  
allows
the user to programmatically change these values? Or JMX? Or just two sets  
of
properties, one for full reindexing and one for 'normal' use?
I somehow like the idea of a management API. Via this API you could set  
the indexing
parameters, but also trigger eg full index rebuilds or index optimizations.


+1 to the API. Currently I use an external process to kick off full builds
and it overrides the 'default' normal use values. I agree the use of an API
would
provide the most flexibility and also eliminate external processes for full
builds.


JMX would be nice as well. It would allow to change parameters on the fly
and allow easy fine-tuning.


I really can't comment on JMX I've never had the time to learn it.

Agreed. Documentation in general needs some work. I found it very hard to  
find some information
about Hibernate projection. It had to work my way backwards from a  
projection testcase in HSearch.
I think HSearch with projections is a great step forward, but we need some  
code examples so
that people can see how to use them. I will try to add something to the  
wiki.
