[opencms-dev] How can I index my custom-properties?

[Claus Priisholm]

While we're at it...

As I understand the search setup, as it is currently, does not provide 
provide a 'negative' list.

I have some shared content folders at the root of the site and a number 
of locale specific folders as well. Now I would like to build an index 
per locale, each index should include the locale folder as well as all 
the shared folders.

So a german index should include "/" except "/en" and "/da", the danish 
should include "/" except "/en" and "/de" and so forth. Making just one 
big index on "/" and then use root filtering is not ideal since the 
differences in stop words and stemming algorithms. And it is my 
understanding that it is the locale definition per index in the setup 
that controls whether say german or english stemming is used, not the 
locale for the resource.

I'll try to dig up some changes that I did on Matt's OC5 lucene module 
to that end (I seem to recall I also added a specific property that 
would control per file if it would be indexed or not - the 
index-property in OC 6 seem to be reserved for some other purpose)

regards
Claus
