[Zope-CMF] get empty list from Contributors in search results

[Grégoire Weber]

Hi Tres,

(forgot the list first)

first of all: it works! Thanks! 
Second: Zope is really a wonderful tool! (CMF also!!!)

Aha, it seems as I have to have a look at this once ... I followed the
discussion last year (?) but didn't understand entirely. 

It works if I fetch the Contributors by <dtml-var
"getObject().Contributors()">
(instead of <dtml-var Contributors>).

How serious is the performance penalty?

I didn't find the "Schema" tab but I added Contributors as Field 
Index at the "Indexes" tab and additionally in the "Metadata" 
tab (Information just for people on the list).

Just for curiosity:

Is my understanding correct that an index is much the same as the 
alphabetical index at the end of a book (a list of words and the
reference to the page/object (book/catalog) where the word occures) 
and that in metadata the content of property is saved/cached?

So by adding a property to the index I make it (the property) 
searchable and by adding it to metadata I make it fetchable 
directly from the catalog.

Correct?

Greg
