Namazu-users-en(old)

[jusob@xxxxxxx]

Hello
I have again an other question!
I've seen in the manual, that it is possible to do different queries (and, 
or,...)
But when I try, for exemple (I'm working on german documents):
namazu das or nichts /xxx/index , it returns only the document wich have the 
word 'das' inside:
(or) [ (The index should be old format.) ]
(nichts) [ (The index should be old format.) ]
(/xxx/index) [das: 0]
No document matching your query

But when I search nichts or das, it founds one document.
So, is the query only for namazu.cgi? Or how could I use a 'complex' query with

the command line namazu?

Thanks again
