problems encountered when packagin and installing the index

Hi,
I could not successfully package and install the pre-build index to prevent
indexing…the following is what I did…Thanks.
I have a QNX 6.3.0 OS with SP2. I have followed the instructions given by
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/misc/help_product_index.html,
and I have successefully created doc_index.zip. The doc_index.zip is under
/build/com.my.plugin/nl/en. I have tried the following to package and
install the index.:
First, I created a plugin_customization.ini that contains the entry
(I have tried both org.eclipse.help.base and org.eclipse.help.base_3.0.1)
org.eclipse.help.base_3.0.1/productIndex=com.my.plugin, and paste that ini
file and the /nl/en/doc_index.zip under the follwing,
org.eclipse.help_3.0.0
org.eclipse.help.webapp_3.0.1
org.eclipse.help.ui_3.0.0
org.eclipse.help.ide_3.0.0
org.eclipse.help.base_3.0.1 org.eclipse.help.appserver_3.0.0

However, I could not prevent indexing from occuring. So, I tried the
following too…I modify the plugin_customization.ini file to
(I have tried both with version specified and no version specified)
org.eclipse.help.base_3.0.1/productIndex=com.qnx.tools.ide.doc.pe_3.0.0 ,and
I have paste the .ini file under org.eclipse.help_3.0.0

org.eclipse.help.webapp_3.0.1
org.eclipse.help.ui_3.0.0
org.eclipse.help.ide_3.0.0
org.eclipse.help.base_3.0.1 org.eclipse.help.appserver_3.0.0
but still could not prevent indexing.
In both case I have renamed the workspace. Please be so kind to see what I
am doing wrong here. Thanks for your help.
