Help needed: Search function for custom Repository Manager

Question

Hi there,
i'm writing my own Repository Manager for EP 6.0 SP2 PL4.
I've serious problems getting the search function running. I'm using the 'new', Netweaver-based API.
I think, there are some general questions to answer:
- My Repository Manager exposes lots of custom 
   properties to the system. I create the properties
   for example using following code:
   IProperty newProp = new StringSingleValueProperty(
     PropertyName.getPropertyName(
              "{}" + myAttName),
     myAttVal,                         PropertyFlags.constructFlags(
              true, false, true, false)
    Is there any convention for the propertie's name?
    I think it has to be written in lowercase only?
    Can I use ANY namespace I want instead of the
    empty default namespace? (For example:
- After indexing my resources (of course, containing my
   custom properties), the TREX-Monitoring screen for my
   index shows all my custom properties in the 'Document
   Properties' area, but all uppercase chars are escaped
   somewhat. Is this OK?
- Trying to use the index above to search for particular
   resources in my repository by my custom properties
   fails all the time ('no docs found...'); searching for
   any system property works fine. What's the reason?
- How can I force the (Property-) search uses my
   custom namespace-manager's methods
   isQueryPropertyNameUnderstood() and
   getQueryBuilder()
   to perform a 'pure' property search by the repository
   manager? It seems that the TREX always handles the
   queries by itself, because my methods are never called.
Thanx for you help,
Daniel

Answer 1

I created a new manager and copied the classes exactly from the "simple" example and I see similar behavior. Actually, when I do this, folders are recursively copied, but not files. Again, browsing and viewing of files work fine. Again, I am not seeing any unexpected exceptions.
The only thing that changed were the names and namespaces. Nothing else at all was changed.
This makes me think I am missing some configuration somewhere or there is something special about the example project that the wizards are not creating. The only difference I see in the project file is an additional nature (com.tssap.selena.cmf.PatternNature), but I am not sure that is relevant.
Wow, I am really stumped.
