I have an setup with aliases like that:

> Index: 2009\_12  
> aliases:  
> 2009  
> test-index\_de\_2009 (filter)  
> test\_de\_2009 (filter)

If I use 2009/\_search or 2009\_12/\_search i get all documents.  
if I use test\_de\_2009/\_search i get only the documents on a filtered field "name". I have the same filtered function with test-index\_de\_2009 and the "name" field, but i get no results when i search with test-index\_de\_2009/\_search.

Whats the reason? I think its the hyphen, but i dont know why this happen and how to fix it.

regards  
andi

Can you share the alias creation commands you used?

"db" is the filtered alias field and has default mapping (string, standard analyzer).
