[Moin-user] Moin1.6a with XAPIAN (help and attachment support)

Make very sure --wiki-url is correct and it will match whatever you 
configured in wikiconfig/farmconfig.

 From the stuff you posted below, it rather looks like it is:

--wiki-url=home.heavy.ch:8080/

But usually you get some error if it does not match.

Most pages will work, but some stuff can break.

                    ^^^^^^^^^^^^^^^^^

This is your problem.

> Xapian Version
>         1.0.2
> Stemming for Xapian
>         Disabled
 > PyStemmer Version
 >         PyStemmer not installed
 > PyStemmer stems
 >         NONE

Maybe installing PyStemmer is a good idea (but not related to your 
trouble, I guess).

> d) but if I'm starting to search it changes to:
> Xapian search
>         Disabled

If moin doesn't find a xapian index, moin will auto-disable xapian_search.

Look there: http://master.moinmo.in/HelpOnXapian

(master has 1.6 content, everything else is still 1.5)

BTW, if you get it working, you can help us by doing ACL tests with xapian.

Just index some pages and attachments that are not readable for user X.

Then search for stuff on those pages with user X.

Does it find pages or attachments it should not find for X because ACLs 
normally limit reading of the stuff for user X?

Yes, everything we have a filter for (see MoinMoin/filter/ - some stuff 
there [esp. the M$ stuff] needs additional software installed).

Some other stuff (*.iso, *.zip, *.tar.gz, ...) is excluded from indexing.

Also look into docs/CHANGES, some of the stuff should be documented there.
